Adhemerval Zanella 689724e578 [compiler-rt] [msan] Unify aarch64 mapping 
This patch unify the 39-bit and 42-bit mapping for aarch64 to use only
one instrumentation algorithm.  A runtime check avoid mapping 42-bit 
only segments for 39-bit kernels.

The mapping to use now is for 39 and 42-bits:

    0x00000000000ULL-0x01000000000ULL  MappingDesc::INVALID
    0x01000000000ULL-0x02000000000ULL  MappingDesc::SHADOW
    0x02000000000ULL-0x03000000000ULL  MappingDesc::ORIGIN
    0x03000000000ULL-0x04000000000ULL  MappingDesc::SHADOW
    0x04000000000ULL-0x05000000000ULL  MappingDesc::ORIGIN

    0x07000000000ULL-0x08000000000ULL  MappingDesc::APP

And only for 42-bits:

    0x08000000000ULL-0x09000000000ULL  MappingDesc::INVALID
    0x09000000000ULL-0x0A000000000ULL  MappingDesc::SHADOW

    0x3E000000000ULL-0x3F000000000ULL  MappingDesc::ORIGIN
    0x3F000000000ULL-0x40000000000ULL  MappingDesc::APP

And although complex it provides a better memory utilization that
previous one.

memcmp_test.cc
[asan,tsan,msan] move the memcmp interceptor from asan/tsan to sanitizer_common. This may potentially lead to more reports from msan as it now sees the reads inside memcmp. To disable, use the flag intercept_memcmp=0. Likewise, it may potentially cause new races to appear due to more strict memcmp checking (flag strict_memcmp=1)
