Improve reload inheritance's code generation and predictability

Updated version taking into account comments from various individuals.  Compile
time cost is down to less than .25% according to my testing.

Patch to combine several distinct arrays into a single VEC

Patch to move various reg_equiv_xxx arrays into a single structure to ease
debugging and growing the structures in response to creating new pseudos.

About .1% compile-time slowdown, possibly due to the checking built into the
VEC implementation.

Minor improvement to register allocation

Was showing good results for x86; however, was regressing for mn103 and put on
indefinite hold pending resolution of the regressions.  While it's on hold, I
don't want it to get lost completely.

Andy's frame-pointerless mcount patch

This is Andy's frame-pointerless mcount patch.  There was a thread on one of
the lists about this patch, but I couldn't find it in my quick search.  Again,
moving it here so it doesn't get lost.

Before closing this, all pending patches from 4.7 should be moved to the 4.8
meta-bug. Otherwise, they will get lost. It wouldn't be the first time that
patches are lost.

All of those patches have already been lost as far as I can see.  Most of them
are over a year old and some have been in the pending patches meta-bug for 2 or
3 major releases already.
