The ASanified executable could be launched from different locations. When we
cannot find the suppression file relative to the current directory, try to

[Sanitizer] Fix report_path functionality:
...
Summary:
- Make sure mmap() is never called inside RawWrite function.
- Wrap a bunch of standalone globals in a ReportFile object.
- Make sure accesses to these globals are thread-safe.
- Fix report_path functionality on Windows, where
__sanitizer_set_report_path() would break program.
I've started this yak shaving in order to make
"CommonFlags::mmap_limit_mb" immutable. Currently we drop this flag
to zero before printing an error message.

[Sanitizer] Make StackTrace a lightweight reference to array of PCs, and

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.

PR20721: Don't let UBSan print inaccessible memory
...
Summary:
UBSan needs to check if memory snippet it's going to print resides
in addressable memory. Similar check might be helpful in ASan with
dump_instruction_bytes option (see http://reviews.llvm.org/D5167 ).
Instead of scanning /proc/self/maps manually, delegate this check to
the OS kernel: try to write this memory in a syscall and assume that
memory is inaccessible if the syscall failed (e.g. with EFAULT).
Fixes PR20721.

renamed to internal_getpid, bringing the Linux variant into use.

This change moves to a model where the error value of a system call is
potentially contained in the return value itself rather than being
implicit in errno. The helper function internal_iserror can be used
to extract the error value from a return value. On platforms other
than Linux/x86_64 this still uses errno, but other platforms are free
to port their error handling to this new model.
