Inlining and estimate_num_insns

[Benjamin Redelings I]

Hello,

	I would be interested in testing patches that you produce.  It seems 
that inlining heuristics have quite a large effect on my code, compared 
to other codes.

	As an aside, do you (or anyone) know what kind of compile-time speedup 
can be gained by boostrapping with more extreme options?  For example 
"-O3 -mpentium4 -fomit-frame-pointer" on PIV processors?
