It's a simpler, faster, and more portable.

SuppressionContext is no longer a singleton, shared by all sanitizers,
but a regular class. Each of ASan, LSan, UBSan and TSan now have their
own SuppressionContext, which only parses suppressions specific to
that sanitizer.
"suppressions" flag is moved away from common flags into tool-specific
flags, so the user now may pass
ASAN_OPTIONS=suppressions=asan_supp.txt LSAN_OPIONS=suppressions=lsan_supp.txt
in a single invocation.

Extending SuppressionContext to add a HasSuppressionType method that tells whether a certain suppression type is currently used or not. It's a step to implement issue suppressions for ASan, see http://reviews.llvm.org/D6280.

more robust in case we failed to extract a stack trace for one of the locks

LibIgnore allows to ignore all interceptors called from a particular set
of dynamic libraries. LibIgnore remembers all "called_from_lib" suppressions
from the provided SuppressionContext; finds code ranges for the libraries;
and checks whether the provided PC value belongs to the code ranges.
Also make malloc and friends interceptors use SCOPED_INTERCEPTOR_RAW instead of
SCOPED_TSAN_INTERCEPTOR, because if they are called from an ignored lib,
then must call our internal allocator instead of libc malloc.

not it's possible to write more precise suppressions,
e.g. "^foo$" won't match "blafoobar"

Factor out code to be reused in LSan. Also switch from linked list to vector.
