David Chase 378a863682 [dev.ssa] cmd/compile: enhance command line option processing for SSA 
The -d compiler flag can also specify ssa phase and flag,
for example -d=ssa/generic_cse/time,ssa/generic_cse/stats

Spaces in the phase names can be specified with an
underscore.  Flags currently parsed (not necessarily
recognized by the phases yet) are:

   on, off, mem, time, debug, stats, and test

On, off and time are handled in the harness,
debug, stats, and test are interpreted by the phase itself.

The pass is now attached to the Func being compiled, and a
new method logStats(key, ...value) on *Func to encourage a
semi-standardized format for that output.  Output fields
are separated by tabs to ease digestion by awk and
spreadsheets.  For example,
	if f.pass.stats > 0 {
		f.logStat("CSE REWRITES", rewrites)
	}
