The Grow method is like the proposed slices.Grow function
in that it ensures that the slice has enough capacity to append
n elements without allocating.
The implementation of Grow is a thin wrapper over runtime.growslice.
This also changes Append and AppendSlice to use growslice under the hood.

The testasan test was added back in 2013 (CL 10126044), many years
before Go added ASAN support in 2021 (CL 298611). So, in fact,
testasan does not test Go ASAN support at all, as you might expect
(misc/cgo/testsanitizers does that). It's intended to test whether the
Go memory allocator works in a mixed C/Go binary where the C code is
compiled with ASAN. The test doesn't actually use ASAN in any way; it
just simulates where ASAN of 2013 put its shadow mappings. This made
sense to test at the time because Go was picky about where its heap
landed and ASAN happened to put its mappings exactly where Go wanted
to put its heap. These days, Go is totally flexible about its heap
placement, and I wouldn't be surprised if ASAN also works differently.
Given all of this, this test adds almost no value today. Drop it.
For #37486, since it eliminates a non-go-test from dist.

The existing version of this test contains several races it tries to
control with sleeps. Unfortunately, it is still flaky on darwin because
writing `fg` in bash too early can apparently result in failure to
actually continue the stopped child.
Rather than continuing to get perfect timing with bash, rewrite this to
eliminate bash and instead perform the same PTY operations that bash
would do.
This test is still quite complex because psuedo-terminals are
interminably complicated, but I believe it is no longer racy.
Technically there are still two races (waiting for child to enter read()
and waiting for the darwin kernel to wake the read after TIOCSPGRP), but
loss of either of these races should only mean we fail to test the
desired darwin EINTR case, not failure.

This adds the function "start line number" to runtime._func and
runtime.inlinedCall objects. The "start line number" is the line number
of the func keyword or TEXT directive for assembly.
Subtracting the start line number from PC line number provides the
relative line offset of a PC from the the start of the function. This
helps with source stability by allowing code above the function to move
without invalidating samples within the function.
Encoding start line rather than relative lines directly is convenient
because the pprof format already contains a start line field.
This CL uses a straightforward encoding of explictly including a start
line field in every _func and inlinedCall. It is possible that we could
compress this further in the future. e.g., functions with a prologue
usually have <line of PC 0> == <start line>. In runtime.test, 95% of
functions have <line of PC 0> == <start line>.
According to bent, this is geomean +0.83% binary size vs master and
-0.31% binary size vs 1.19.
Note that //line directives can change the file and line numbers
arbitrarily. The encoded start line is as adjusted by //line directives.
Since this can change in the middle of a function, `line - start line`
offset calculations may not be meaningful if //line directives are in
use.

LookupFieldOrMethod appears as a hotspot when benchmarking gopls'
auto-completion. In particular, instanceLookup.add was allocating in the
common case of structs with no embedding.
This is easily fixed, by using a small array in front of the map inside
of instanceLookup. Do this, and additionally add a microbenchmark.
The benchmark improvement is significant:
name old time/op new time/op delta
LookupFieldOrMethod-12 388µs ± 6% 154µs ± 3% -60.36% (p=0.000 n=10+10)
name old alloc/op new alloc/op delta
LookupFieldOrMethod-12 152kB ± 0% 2kB ± 0% -98.77% (p=0.000 n=9+10)
name old allocs/op new allocs/op delta
LookupFieldOrMethod-12 1.41k ± 0% 0.07k ± 0% -95.38% (p=0.000 n=10+10)
It should also be noted that instanceLookup is used elsewhere, in
particular by validType. In those contexts, the scope is not just the
current type but the entire package, and so the newly added buffer is
likely to simply cause extra Identical checks. Nevertheless, those
checks are cheap, and on balance the improved LookupFieldOrMethod
performance leads overall to improved type-checking performance.
Standard library benchmark results varied by package, but type checking
speed for many packages improved by ~5%, with allocations improved by
~10%. If this weren't the case we could let the caller control the
buffer size, but that optimization doesn't seem necessary at this time.
For example:
Check/http/funcbodies/noinfo-12 71.5ms ± 4% 67.3ms ± 2% -5.90% (p=0.000 n=20+20)
Check/http/funcbodies/noinfo-12 244k ± 0% 219k ± 0% -10.36% (p=0.000 n=19+19)

This change adds an API to the runtime for arenas. A later CL can
potentially export it as an experimental API, but for now, just the
runtime implementation will suffice.
The purpose of arenas is to improve efficiency, primarily by allowing
for an application to manually free memory, thereby delaying garbage
collection. It comes with other potential performance benefits, such as
better locality, a better allocation strategy, and better handling of
interior pointers by the GC.
This implementation is based on one by danscales@google.com with a few
significant differences:
* The implementation lives entirely in the runtime (all layers).
* Arena chunks are the minimum of 8 MiB or the heap arena size. This
choice is made because in practice 64 MiB appears to be way too large
of an area for most real-world use-cases.
* Arena chunks are not unmapped, instead they're placed on an evacuation
list and when there are no pointers left pointing into them, they're
allowed to be reused.
* Reusing partially-used arena chunks no longer tries to find one used
by the same P first; it just takes the first one available.
* In order to ensure worst-case fragmentation is never worse than 25%,
only types and slice backing stores whose sizes are 1/4th the size of
a chunk or less may be used. Previously larger sizes, up to the size
of the chunk, were allowed.
* ASAN, MSAN, and the race detector are fully supported.
* Sets arena chunks to fault that were deferred at the end of mark
termination (a non-public patch once did this; I don't see a reason
not to continue that).

fakePC uses hash.Sum32, which returns an uint32. However, libfuzzer
trace/hook functions declare fakePC argument as int, causing overflow on
386 archs.
Fixing this by changing fakePC argument to uint to prevent the overflow.

The errorcalls_test makes sure that we use error instead of errorf
where possible. Copied from types2 and adjusted for go/types.

least 4 arguments.

This brings go/types error reporting closer to types2.
Except for removing the error functions and one manual correction,
these changes were made by regex-replacing:
check\.invalidAST\((.*), " =>
check.errorf($1, InvalidSyntaxTree, invalidAST+"
check\.invalidOp\((.*), " =>
check.errorf($1, invalidOp+"
check\.invalidArg\((.*), " =>
check.errorf($1, invalidArg+"
A follow-up CL ensures that we use error instead of errorf where
possible.
