cmd/compile: get gcflags to bootstrap; ssa debug opts for "all"
This is intended to help debug compiler problems that pop
up in the bootstrap phase of make.bash. GO_GCFLAGS does not
normally apply there. Options-for-all phases is intended
to allow crude tracing (and full timing) by turning on timing
for all phases, not just one.
Phase names can also be specified using a regular expression,
for example
BOOT_GO_GCFLAGS=-d='ssa/~^.*scc$/off' \
GO_GCFLAGS='-d=ssa/~^.*scc$/off' ./make.bash
I just added this because it was the fastest way to get
me to a place where I could easily debug the compiler.
