[dev.regabi] cmd/compile: introduce cmd/compile/internal/base [generated]

Browse source 
Move Flag, Debug, Ctxt, Exit, and error messages to
new package cmd/compile/internal/base.

These are the core functionality that everything in gc uses
and which otherwise prevent splitting any other code
out of gc into different packages.

A minor milestone: the compiler source code
no longer contains the string "yy".
