ParseUnixMemoryProfile assumes well-formed input with \n at the end, etc.
It can over-read the input and crash on basically every line
in the case of malformed input.
ReadFileToBuffer has cap the max file size (64MB) and returns
truncated contents if the file is larger. Thus even if kernel behaves,
ParseUnixMemoryProfile crashes on too large /proc/self/smaps.
Fix input over-reading in ParseUnixMemoryProfile.
Depends on D112792.

stats_size argument is unnecessary in GetMemoryProfile and in the callback.
It just clutters code. The callback knowns how many stats to expect.

Move parsing of /proc/self/smaps into a separate function
so that it can be tested.

size() is inconsistent with length().
In most size() use cases we can replace InternalScopedString with
InternalMmapVector.
Remove non-constant data() to avoid direct manipulations of internal
buffer. append() should be enought to modify InternalScopedString.

Revert "Fix compiler-rt build on Windows after D89640"
This reverts commit a7acee89d6.
This reverts commit d09b08919c.
Reason: breaks Linux / x86_64 build.
See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done
and manually updated (many) references to renamed files found by that.
