Summary:
Reduce RSS size treshold in the unit test to accomodate for the smaller
ASAN quarantine size on Android (see D27873).

Use some new substitutions to avoid duplicating the tests for just
dropped flags. -fPIC/-fPIE/-fpic/-fpie do not make sense on Windows as
they can cause ELF-style PIC. Substitute away the flag on Windows.
This should repair the windows buildbots.

Updated test according to commit 290539:
According to extended asm syntax, a case where the clobber list includes a variable from the inputs or outputs should be an error - conflict.
for example:
const long double a = 0.0;
int main()
{
char b;
double t1 = a;
__asm__ ("fucompp": "=a" (b) : "u" (t1), "t" (t1) : "cc", "st", "st(1)");
return 0;
}
This should conflict with the output - t1 which is st, and st which is st aswell.
The patch fixes it.

Fix missing "int_lib.h" includes in ARM negdf2vfp and subdf3vfp tests.
Additionally, extend the __arm__ guard to cover the builtin definition
in the former. This is mostly intended to prevent build failures
and allow those tests to be properly skipped on other targets.

Summary:
With the previous modifications, the code works on ARM32. The random shuffle
test is unsupported on 32-bit platforms for the moment and being marked as
such. There is no hardware support for the checksum computation yet, this will
come at a later point.

Summary:
After rL289878/rL289881, the build on FreeBSD is broken, because
sanitizer_platform_limits_posix.cc attempts to include <utmp.h> and use
`struct utmp`, neither of which are supported anymore on FreeBSD.
Fix this by adding `&& !SANITIZER_FREEBSD` in a few places, and stop
intercepting utmp functions altogether for FreeBSD.

In ASan, we have __asan_locate_address and __asan_get_alloc_stack, which is used in LLDB/Xcode to show the allocation backtrace for a heap memory object. This patch implements the same for TSan.

llvm-svn: 290079
Summary:
Getting rid of the distance number altogether because:
- a person knowledgeable enough to know what the message means will also
know how to do hexadecimal math (with the help of a calculator)
- numbers outside INT_MIN - INT_MAX are hard to comprehend anyway
This unbreaks the case when you dynamically link a library with XRay and
it exits pre-main() with a not very informative static string.

Remove the trailing name on the `.endm` which does not take the name of the
macro. This should bring the compiler-rt build bot back into working state.

Summary:
With the recent changes to the Secondary, we use less bits for UnusedBytes,
which allows us in return to increase the bits used for Offset. That means
that we can use a Primary SizeClassMap allowing for a larger maximum size.
