Cherry Zhang 5d7dc53888 [dev.regabi] cmd/compile, runtime: reserve R14 as g registers on AMD64
This is a proof-of-concept change for using the g register on
AMD64. getg is now lowered to R14 in the new ABI. The g register
is not yet used in all places where it can be used (e.g. stack
bounds check, runtime assembly code).
