When we're compiling a resultInArg0 op, we need to clobber the
register containing the input value. So we first make a register copy
of the input value. We can then clobber either of the two registers
the value is in and still have the original input value in a register
for future uses.
Before this CL, we always clobbered the original, not the copy.
But that's not always the right decision - if the original is already
in a specific register that it needs to be in later (typically, a
return value register), clobber the copy instead.
This optimization can remove a mov instruction. It saves 1376 bytes
of instructions in cmd/go.

When calling a c library function, you discover that an error has
occurred, typically by looking at the return value of the function. Only
after that can you use errno to figure out the cause of the error.
Nothing about cgo changes that story -- you still have to look at the
result before checking the error that represents errno. If not you can
get false errors if the function happens to leak a non-zero errno.
Fix testpty to check errors correctly.

This also makes path/filepath.Walk more consistent between
Windows and POSIX platforms.
According to
https://pubs.opengroup.org/onlinepubs/9699919799.2013edition/basedefs/V1_chap04.html#tag_04_12
symlinks in a path that includes a trailing slash must be resolved
before a function acts on that path.
POSIX defines an lstat function, whereas the Win32 API does not, so
Go's os.Lstat should follow the (defined) POSIX semantics instead of
doing something arbitrarily different.
CL 134195 added a test for the correct POSIX behavior when os.Lstat is
called on a symlink. However, the test turned out to be broken on Windows,
and when it was fixed (in CL 143578) it was fixed with different Lstat
behavior on Windows than on all other platforms that support symlinks.
In #50807 we are attempting to provide consistent symlink behavior for
cmd/go. This unnecessary platform difference, if left uncorrected,
will make that fix much more difficult.
CL 460595 reworked the implementation of Stat and Lstat on Windows,
and with the new implementation this fix is straightforward.
For #50807.

The existing implementation does a float64 to int64 conversion in order to check whether the number is odd, however it does not check for overflows. If an overflow occurs, the result is implementation-defined and while it happens to work on amd64 and i386, it produces an incorrect result on arm64 and possibly other architectures.
This change fixes that and also avoids calling isOddInt altogether if the base is +0, because it's unnecessary.
(I was considering avoiding the extra check if runtime.GOARCH is "amd64" or "i386", but I can't see this pattern being used anywhere outside the tests. And having separate files with build tags just for isOddInt() seems like an overkill)

Since it was added, back on https://golang.org/cl/5797068, it has caused

Prior to this change (as of CL 143578), our stat function attempted to
resolve all reparse points as if they were symlinks.
This results in an additional call to CreateFile when statting a
symlink file: we use CreateFile once to obtain the reparse tag and
check whether the file is actually a symlink, and if it is we call
CreateFile again without FILE_FLAG_OPEN_REPARSE_POINT to stat the link
target. Fortunately, since symlinks are rare on Windows that overhead
shouldn't be a big deal in practice.

This CL redesign how we get the TLS pointer on windows/i386.
It applies the same changes as done in CL 431775 for windows/amd64.
We were previously reading it from the [TEB] arbitrary data slot,
located at 0x14(FS), which can only hold 1 TLS pointer.
With this CL, we will read the TLS pointer from the TEB TLS slot array,
located at 0xE10(GS). The TLS slot array can hold multiple
TLS pointers, up to 64, so multiple Go runtimes running on the
same thread can coexists with different TLS.
Each new TLS slot has to be allocated via [TlsAlloc],
which returns the slot index. This index can then be used to get the
slot offset from GS with the following formula: 0xE10 + index*4.
The slot index is fixed per Go runtime, so we can store it
in runtime.tls_g and use it latter on to read/update the TLS pointer.
Loading the TLS pointer requires the following asm instructions:
MOVQ runtime.tls_g, AX
MOVQ AX(FS), AX
Notice that this approach will now be implemented in all the supported
windows arches.

Previously TryBot-tested with bucket bits = 4.
Also tested locally with bucket bits = 5.
This makes it much easier to change the size of map
buckets, and hopefully provides pointers to all the
code that in some way depends on details of map layout.

If OpArgIntReg is incorrectly scheduled, that causes it to be spilled
incorrectly, which causes the argument to not be considered live
at the start of the function.
This is the test for CL 462858
Add a brief mention of why CL 462858 is needed in the scheduling code.

Sort variables before display so that when there are multiple variables
to report, they are in a consistent order.
Otherwise they are ordered in the order they appear in the fn.Dcl list,
which can vary. Particularly, they vary depending on regabi.
