[TSan] Keep original function and filename in ReportStack.
TSan used to do the following transformations with data obtained
from the symbolizer:
1) Strip "__interceptor_" prefix from function name.
2) Use "strip_path_prefix" runtime flag to strip filepath.
Now these transformations are performed right before the stack trace
is printed, and ReportStack structure contains original information.
This seems like a right thing to do - stripping is a detail of report
formatting implementation, and should belong there. We should, for
example, use original path to source file when we apply suppressions.
This change also make "strip_path_prefix" flag behavior in TSan
consistent with all the other sanitizers - now it should actually
match *the prefix* of path, not some substring. E.g. earlier TSan
would turn "/usr/lib/libfoo.so" into "libfoo.so" even if strip_path_prefix
was "/lib/".
Finally, strings obtained from symbolizer come from internal allocator,
and "stripping" them early by incrementing a "char*" ensures they can
never be properly deallocated, which is a bug.

Appropriately set/clear the FeatureBit for Mips16 when these assembler directives are used and also emit ".set nomips16" (previously, only ".set mips16" was being emitted).
These improvements allow for better testing of the .cpload/.cprestore assembler directives (which are not supposed to work when Mips16 is enabled).
Test Plan: The test is bare-bones because there are no MC tests for Mips16 instructions (there's only one, which checks that the Mips16 ELF header flag gets set), and that suggests to me that it has not been implemented yet in the IAS.

bytes_read = target_sp->ReadMemory(addr_priv, false, buf, size, err_priv);
This is wrong. If you get the file addresss from the "addr" argument and try to read memory using that, it will think the file address is a load address and it will try to resolve it accordingly. This will work fine if your executable is loaded at the same address (no slide), but it won't work if there is a slide.
The fix is to just pass along the "addr.ref()" instead of making a new addr_priv as this will pass along the lldb_private::Address that is inside the SBAddress (which is what we want), and not always change it into something that becomes a load address (if we are running), or abmigious file address (think address zero when you have 150 shared libraries that have sections that start at zero, which one would you pick). The main reason for passing a section offset address to SBTarget::ReadMemory() is so you _can_ read from the actual section + offset that is specified in the SBAddress.

PECOFF: Use the string table for long section names in EXEs/DLLs
Normally, PE files have section names of eight characters or less.
However, this is problematic for DWARF because DWARF section names are
things like .debug_aranges.
Instead of truncating the section name, redirect the section name into
the string table.

Lower __builtin_fabs* to @llvm.fabs.*
mingw64's headers implement fabs by calling __builtin_fabs, so using the

Use AA in LoadCombine
LoadCombine can be smarter about aborting when a writing instruction is
encountered, instead of aborting upon encountering any writing instruction, use
an AliasSetTracker, and only abort when encountering some write that might
alias with the loads that could potentially be combined.
This was originally motivated by comments made (and a test case provided) by
David Majnemer in response to PR21448. It turned out that LoadCombine was not
responsible for that PR, but LoadCombine should also be improved so that
unrelated stores (and @llvm.assume) don't interrupt load combining.

[TSan] Use StackTrace from sanitizer_common where applicable
Summary:
This change removes `__tsan::StackTrace` class. There are
now three alternatives:
# Lightweight `__sanitizer::StackTrace`, which doesn't own a buffer
of PCs. It is used in functions that need stack traces in read-only
mode, and helps to prevent unnecessary allocations/copies (e.g.
for StackTraces fetched from StackDepot).
# `__sanitizer::BufferedStackTrace`, which stores buffer of PCs in
a constant array. It is used in TraceHeader (non-Go version)
# `__tsan::VarSizeStackTrace`, which owns buffer of PCs, dynamically
allocated via TSan internal allocator.
