Summary:
In this change we apply `XRAY_NEVER_INSTRUMENT` to more functions in the
profiling implementation to ensure that these never get instrumented if
the compiler used to build the library is capable of doing XRay
instrumentation.
We also consolidate all the allocators into a single header
(xray_allocator.h) which sidestep the use of the internal allocator
implementation in sanitizer_common.
This addresses more cases mentioned in llvm.org/PR38577.

Summary:
Enables trace-malloc-unbalanced.test on Windows, fixing two problems it had with Windows before.
The first fix is specifying python instead of relying on a script's shebang since they can't be used on Windows.
The second fix is making the regex tolerate windows' implementation of the "%p" format string.

Summary:
When targeting MSVC: compile using clang's cl driver mode (this is needed for
libfuzzer's exit_on_src_pos feature). Don't use -lstdc++ when linking,
it isn't needed and causes a warning.
On Windows: Fix exit_on_src_pos.test by making sure debug info isn't
overwritten during compilation of second binary by using .exe extension.

Summary:
When building without COMPILER_RT_HWASAN_WITH_INTERCEPTORS, skip
interceptors for malloc/free/etc and only export their versions with
__sanitizer_ prefix.
Also remove a hack in mallinfo() interceptor that does not apply to
hwasan.

Add the __msan_va_arg_origin_tls TLS array to keep the origins for variadic function parameters.
Change the instrumentation pass to store parameter origins in this array.
This is a reland of r341528.
test/msan/vararg.cc doesn't work on Mips, PPC and AArch64 (because this
patch doesn't touch them), XFAIL these arches.
Also turned out Clang crashed on i80 vararg arguments because of
incorrect origin type returned by getOriginPtrForVAArgument() - fixed it
and added a test.

MachO symbols are prefixed with an extra '_' (that's 3 in total for this
function), so assembly calls have to go through a wrapper to insert any prefix
needed.

Sigtrap is used for error reporting, but all other signals are better
left for the platform.
In particular, sanitizer signal handlers do not dump registers or
memory which makes debugging harder for no good reason.

Summary:
Enable tests on Windows and make check-fuzzer pass on it. Make
check-fuzzer pass on Windows by fixing libFuzzer, fixing tests, and by
disabling tests on Windows. Most of these are disabled temporarily as
support for the tests and the features they test will be added
incrementally. Other tests will not be enabled since they require
things that are not on Windows (eg: afl_driver tests). Every test
that was explicitly disabled on Windows has a comment explaining why
(unless obvious like merge-posix.test).
The lit.cfg file was modified to support running tests on windows.
fuzzer-dirs.test was fixed by making the Windows implementation print
the same error message as the posix version.
merge-control-file.test was fixed by making the test binary end with
the ".exe" extension (on all platforms).

* The `fd` arg passed to `mmap()` should be `-1`. It is not defined
what passing `0` does on Darwin.
* The comment about the shadow memory doesn't make any sense to me,
so I'm removing it.

Summary:
Switch local sysctl(2) calls to internal_sysctl().
This is a preparation for introduction of interceptors for
the sysctl*() family of functions and switching `internal_sysctl*()`
to libc calls bypassing interceptors.
No functional change intended with this revision.
