cmd/compile: add -msan option
The -msan option causes the compiler to add instrumentation for the
C/C++ memory sanitizer. Every memory read/write will be preceded by
a call to msanread/msanwrite.
This CL passes tests but is not usable by itself. The actual
implementation of msanread/msanwrite in the runtime package, and support
for -msan in the go tool and the linker, and tests, will follow in
subsequent CLs.
