Currently the callback runs on the caller's stack. If this stack
contains values that have gone out of scope, and we are not super careful, those
values can propagate into global variables (the libc sigaction() in particular
has a side effect that can lead to this). This has caused false negatives in
leak checking code.

Changes: map a separate stack space for the tracer thread. Also, move some
globals into local scope (they had no business being global anyway).

Same interface as in STL. Needed for LSan.

[tsan] restore performance critical inlining in tsan: remove static from ALWAYS_INLINE, use ALWAYS_INLINE USED for critical functions. 

llvm-svn: 178341

This removes all register spills from the performance-critical __tsan_{read,write}{1,2,4,8} functions when the host compiler is GCC.

[ASan] Speed-up initialization-order checking: create and use fast versions of PoisonShadow functions, store copies of __asan_global descriptors in a vector instead of list of pointers. This gives 3x speedup on both benchmarks and real binaries with lots of globals.

Fix unmatching ASan runtime flag for init-order checking exposed by r178158. Add a test for r178158.

[tsan] don't use -fno-builtin for tests; add a test for a false negative bug (inlined memcpy is not instrumented)
