Alex Shlyapnikov 5cd35ed4fe [HWASan] Port HWASan to Linux x86-64 (compiler-rt) 
Summary:
Porting HWASan to Linux x86-64, first of the three patches, compiler-rt part.

The approach is similar to ARM case, trap signal is used to communicate
memory tag check failure. int3 instruction is used to generate a signal,
access parameters are stored in nop [eax + offset] instruction immediately
following the int3 one

Had to add HWASan init on malloc because, due to much less interceptors
defined (most other sanitizers intercept much more and get initalized
via one of those interceptors or don't care about malloc), HWASan was not
initialized yet when libstdc++ was trying to allocate memory for its own
fixed-size heap, which led to CHECK-fail in AllocateFromLocalPool.

Also added the CHECK() failure handler with more detailed message and
stack reporting.
