ARM64: specify triple so that Linux tests pass

Now that Linux is trying to reparse all inline asm it chokes on the different
comment character in this test.

[asan] add two new hidden compile-time flags for asan: asan-instrumentation-with-call-threshold and asan-memory-access-callback-prefix. This is part of the workaround for PR17409 (instrument huge functions with callbacks instead of inlined code). These flags will also help us experiment with kasan (kernel-asan) and clang

[mips] Correct r206370 to account for non-Linux targets using the small data section.

This should fix the ninja-x64-msvc-RA-centos6 builder.

I suspect the check in MipsSubtarget.cpp is incorrect and is really trying to
check for a bare-metal target rather and anything other than linux. I'll
investigate this.
