Add caching to the MemoryMappingLayout class on Linux. This is necessary for the cases when a sandbox prevents ASan from reading the mappings
from /proc/self/maps.
The mappings are currently being cached on each access to /proc/self/maps. In the future we'll need to add an API that allows the client to notify ASan about the sandbox.

introduces history_size parameter that can be used to control trace size at startup

helps to reduce tls size (it's weird to have multi-MB tls)
will help with dynamically adjustable trace size

[asan/tsan] get rid of kPageSize completely in favor of GetPageSizeCached(). This makes the code friendly to more platforms

llvm-svn: 168537

[asan] get rid of some of the uses of kPageSize. The intent is to get rid of it completely to support platforms with multiple possible page sizes.

[asan/tsan] do not use __WORDSIZE macro, as it is glibc-private thing. Instead, define our own SANITIZER_WORDSIZE

[Sanitizer] replace while with internal_memset to make sure compiler won't replace it with library memset

-fsanitize=undefined: Switch to using sanitizer_common for output. This gets us much closer to not depending on any system headers.

tsan: slightly relax requirements for lazy shadow memory (can overlap and may not be properly aligned)
it's problematic on windows where allocation granularity is much larger than page size

The file uses namespaces and extern "LANG", so it's kinda senseless to use #ifdef __cplusplus

__declspec is not _WIN32, it's _MSC_VER

Use internal_memmove() and internal_memcpy() in the memcpy() and memmove() wrappers
when building the dynamic runtime (OS X only), to work around a bug in resolver functions wrapping.
