cmd/compile: add -asan option

The -asan option causes the compiler to add instrumentation for the
C/C++ address sanitizer.  Every memory read/write will be replaced
by a call to asanread/asanwrite.

This CL also inserts asan instrumentation during SSA building.

This CL passes tests but is not usable by itself. The actual
implementation of asanread/asanwrite in the runtime package, and
support for -asan in the go tool and tests, will follow in subsequent
CLs.

Updates #44853.
