introduce a BufferedStackTrace class, which owns this array.

Summary:
This change splits __sanitizer::StackTrace class into a lightweight
__sanitizer::StackTrace, which doesn't own array of PCs, and BufferedStackTrace,
which owns it. This would allow us to simplify the interface of StackDepot,
and eventually merge __sanitizer::StackTrace with __tsan::StackTrace.

Test Plan: regression test suite.

Summary: Make the script suitable for checking just messages. Move most of the tests to use it. Clean up the tests: shorten messages, insert line numbers, remove unnecessary RUN: lines, etc.

This is a simple fix that brings the compilation time from 5min to 5s
on a specific real-world example. It's a large chain of computation in
a crypto routine (always a problem for SCEV). A unit test is not
feasible and there would be no way to check it. The fix is just basic
good practice for dealing with SCEVs, there's no risk of regression.

First, return true on success, as it is the OCaml convention.
Second, also initialize the native assembly printer, which is,
despite the name, required for MCJIT operation.

Since this function did not initialize the assembly printer earlier
and no function to initialize native assembly printer was available
elsewhere, it is safe to break its interface: it means that it
simply could not be used successfully before.

The dividend in "signed % unsigned" is treated as unsigned instead of signed,

We would crash because we used operator[] to access past the end of a
SmallString.  This occured because our token had length zero.

Instead, form the pointer using .data() and arithmetic.  This is safe
because this forms a one-past-the-end pointer and it is only used to
compare with another one-past-the-end pointer.

This fixes PR21379.

Tidied up some entries in the folding tables so that they are under the correct comment section (they were categorised as AVX2 instructions when they're AVX1).

Minor patch agreed with qcolombet.

These asserts can trigger if the worklist iteration order is
sufficiently unlucky.  Instead of adding special case logic to handle
these edge conditions, just bail out on trying to transform them:
InstSimplify will get them when it reaches them on the worklist.

This fixes PR21378.

N.B.  No test case is included because any test would rely on the
fragile worklist iteration order.

In a Mach-O object file a relocatable expression of the form
SymbolA - SymbolB + constant is allowed when both symbols are
defined in a section.  But when either symbol is undefined it
is an error.

The code was crashing when it had an undefined symbol in this case.
And should have printed a error message using the location information
in the relocation entry.

Objective-C switched to a new ABI which uses a different mangling for class
names.  But to keep projects building that use export lists that use the old
class name mangling, the linker recognizes the old names and transforms them
to the new mangling.

In final linked shared images, the __TEXT segment contains both code and
