At the moment this doesn't change anything or fix any bugs because
of the way these two functions are invoked, but that could change

Modify rangefunc #next protocol to make it more robust
Extra-terrible nests of rangefunc iterators caused the
prior implementation to misbehave non-locally (in outer loops).
Add more rangefunc exit flag tests, parallel and tricky
This tests the assertion that a rangefunc iterator running
in parallel can trigger the race detector if any of the
parallel goroutines attempts an early exit. It also
verifies that if everything else is carefully written,
that it does NOT trigger the race detector if all the
parts run time completion.
Another test tries to rerun a yield function within a loop,
so that any per-line shared checking would be fooled.
Added all the use-of-body/yield-function checking.
These checks handle pathological cases that would cause
rangefunc for loops to behave in surprising ways (compared
to "regular" for loops). For example, a rangefunc iterator
might defer-recover a panic thrown in the syntactic body
of a loop; this notices the fault and panics with an
explanation
Modified closure naming to ID rangefunc bodies
Add a "-range<N>" suffix to the name of any closure generated for
a rangefunc loop body, as provided in Alessandro Arzilli's CL
(which is merged into this one).
Fix return values for panicky range functions
This removes the delayed implementation of "return x" by
ensuring that return values (in rangefunc-return-containing
functions) always have names and translating the "return x"
into "#rv1 = x" where #rv1 is the synthesized name of the
first result.

When an M unlocks a contended mutex, it needs to consult a list of the
Ms that had to wait during its critical section. This allows the M to
attribute the appropriate amount of blame to the unlocking call stack.
Mirroring the implementation for users' sync.Mutex contention (via
sudog), we can (in a future commit) use the time that the head and tail
of the wait list started waiting, and the number of waiters, to estimate
the sum of the Ms' delays.
When an M acquires the mutex, it needs to remove itself from the list of
waiters. Since the futex-based lock implementation leaves the OS in
control of the order of M wakeups, we need to be prepared for quickly
(constant time) removing any M from the list.
First, have each M add itself to a singly-linked wait list when it finds
that its lock call will need to sleep. This case is safe against
live-lock, since any delay to one M adding itself to the list would be
due to another M making durable progress.
Second, have the M that holds the lock (either right before releasing,
or right after acquiring) update metadata on the list of waiting Ms to
double-link the list and maintain a tail pointer and waiter count. That
work is amortized-constant: we'll avoid contended locks becoming
proportionally more contended and undergoing performance collapse.

The current stack depth limit for alloc, mutex, block, threadcreate and
goroutine profiles of 32 frequently leads to truncated stack traces in
production applications. Increase the limit to 128 which is the same
size used by the execution tracer.
Create internal/profilerecord to define variants of the runtime's
StackRecord, MemProfileRecord and BlockProfileRecord types that can hold
arbitrarily big stack traces. Implement internal profiling APIs based on
these new types and use them for creating protobuf profiles and to act
as shims for the public profiling APIs using the old types.
This will lead to an increase in memory usage for applications that
use the impacted profile types and have stack traces exceeding the
current limit of 32. Those applications will also experience a slight
increase in CPU usage, but this will hopefully soon be mitigated via CL
540476 and 533258 which introduce frame pointer unwinding for the
relevant profile types.

Previously it was possible for mutex and block profile stack traces to
contain up to 32 frames in Stack0 or the resulting pprof profiles.
CL 533258 changed this behavior by using some of the space to
record skipped frames that are discarded when performing delayed inline
expansion. This has lowered the effective maximum stack size from 32 to
27 (the max skip value is 5), which can be seen as a small regression.
Add TestProfilerStackDepth to demonstrate the issue and protect all
profile types from similar regressions in the future. Fix the issue by
increasing the internal maxStack limit to take the maxSkip value into
account. Assert that the maxSkip value is never exceeded when recording
mutex and block profile stack traces.
Three alternative solutions to the problem were considered and
discarded:
1) Revert CL 533258 and give up on frame pointer unwinding. This seems
unappealing as we would lose the performance benefits of frame
pointer unwinding.
2) Discard skipped frames when recording the initial stack trace. This
would require eager inline expansion for up to maxSkip frames and
partially negate the performance benefits of frame pointer
unwinding.
3) Accept and document the new behavior. This would simplify the
implementation, but seems more confusing from a user perspective. It
also complicates the creation of test cases that make assertions
about the maximum profiling stack depth.
The execution tracer still has the same issue due to CL 463835. This
should be addressed in a follow-up CL.

The posBaseMap is used to identify a file's syntax tree node
given a source position. The position is mapped to the file
base which is then used to look up the file node in posBaseMap.
When posBaseMap is initialized, the file position base
is not the file base if there's a line directive before
the package clause. This can happen in cgo-generated files,
for instance due to an import "C" declaration.
If the wrong file position base is used during initialization,
looking up a file given a position will not find the file.
If a version error occurs and the corresponding file is
not found, the old code panicked with a null pointer exception.
Make sure to consistently initialize the posBaseMap by factoring
out the code computing the file base from a given position.
While at it, check for a nil file pointer. This should not happen
anymore, but don't crash if it happens (at the cost of a slightly
less informative error message).

In dynamic linking mode (e.g. when using plugins) on darwin, the
marker symbols runtime.text and runtime.etext are added to Textp
in an early stage, so when adding symbols to the symbol table we
don't need to explicitly add them. However, when splitting text
sections, the runtime.text.N marker symbols for the addtional
sections are not added to Textp. So we do need to add them
explicitly to the symbol table.
Fixes#66993.

- Replace manual string suffix removal with stringslite.TrimSuffix in conf.go
- Use stringslite.Cut for string splitting in ParseCIDR function in ip.go
- Add stringslite import in ip.go
