Alexander Potapenko 1296436cbf [libsanitizer] Introduce flag descriptions.
Extend ParseFlag to accept the |description| parameter, add dummy values for all existing flags.
As the flags are parsed their descriptions are stored in a global linked list.
The tool can later call __sanitizer::PrintFlagDescriptions() to dump all the flag names and their descriptions.
Add the 'help' flag and make ASan, TSan and MSan print the flags if 'help' is set to 1.

Duncan P. N. Exon Smith ecf2256dfe PGO: Implement Darwin linker magic for instrumentation
Use Darwin linker magic to find bounds of instrumentation data sections
at link time instead of runtime.

Duncan P. N. Exon Smith da0de8a237 PGO: Split out initialization of section bounds
Currently we register instrumentation data at runtime to determine the
bounds of the sections where the data lives.  Soon we'll implement
platform-specific linker magic to determine this at link time.

Move this logic to a separate file, so that our build system can choose
the correct platform-specific code.

No functionality change intended.

Duncan P. N. Exon Smith 8353a26e85 PGO: Splitting implementation files; no functionality change
Split implementation files along a uses-libc/shouldn't-use-libc
boundary.

  - InstrProfiling.h is a shared header.

  - InstrProfiling.c provides an API to extract profiling data from the
    runtime, but avoids the use of libc.  Currently this is a lie:
    __llvm_pgo_write_buffer() uses `FILE*` and related functions.  It
    will be updated soon to write to a `char*` buffer instead.

  - InstrProfilingExtras.c provides a more convenient API for
    interfacing with the profiling runtime, but has logic that does (and
    will continue to) use libc.

Dmitry Vyukov 17efa197bf tsan: fix large stack frame in deadlock detector
In member function 'virtual void __sanitizer::DD::MutexBeforeLock(__sanitizer::DDCallback*, __sanitizer::DDMutex*, bool)':
error: the frame size of 544 bytes is larger than 512 bytes [-Werror=frame-larger-than=]

The code is now [arguably] better as well.

Joerg Sonnenberger 4e08a634e1 Don't take short cuts trying to avoid conditionals. This leads to
negative shift amounts and/or shifts wider than the type. VAX traps on
the former, X86 and other platforms produce incorrect results on the
latter.
