Viktor Kutuzov 68f150f3d4 [Msan] Intercept stat() and fstatat() on FreeBSD

Evgeniy Stepanov a2edd9159a [sanitizer] Make unrecognized flags not fatal. 
Print a warning at verbosity=1 and higher instead of dying immediately.

Evgeniy Stepanov 6c6e589c1f [sanitizer] Switch flag parsing to LowLevelAlloc. 
InternalAlloc is quite complex and its behavior may depend on the values of
flags. As such, it should not be used while parsing flags.

Sadly, LowLevelAlloc does not support deallocation of memory.

Hal Finkel 0e39c55d22 [sanitizer] Adjust max read size in FlagHandlerInclude 
Setting the maximum read size in FlagHandlerInclude to 2^15 might be a good
default, but causes the read to fail on systems with a page size larger than
that (ReadFileToBuffer(...) will fail if the maximum allowed size is less than
the value returned by GetPageSizeCached()). For example, on my PPC64/Linux
system, GetPageSizeCached() returns 2^16. In case the page size is larger, use
that instead.

Justin Bogner 66fd5c914a InstrProf: Optionally print an error when emitting profile data fails

Hal Finkel e67f32aa99 [asan] Loosen test for upcoming ppc64 change 
This test casts 0x4 to a function pointer and calls it. Unfortunately, the
faulting address may not exactly be 0x4 on PPC64 ELFv1 systems. The LLVM PPC
backend used to always generate the loads "in order", so we'd fault at 0x4
anyway. However, at upcoming change to loosen that ordering, and we'll pick a
different order on some targets. As a result, as explained in the comment, we
need to allow for certain nearby addresses as well.

Saleem Abdulrasool a7452e434b builtins: avoid duplicating unwind declarations 
Use unwind.h to get the declarations for unwinding interfaces.  This header is
already provided by clang and gcc, so this adds no additional dependencies for
building the builtins library.  It avoids the duplication which may drift over
time though.

Jay Foad 335c08e56c [ASan] Handle SIGBUS on Linux. 
Summary:
On Linux in some situations we can get SIGBUS instead of SIGSEGV on
stack overflow, so asan should handle SIGBUS as well as SIGSEGV.
