GCC for newer pyramids (i.e. MIServers)

[Torbj|rn Granlund]

--text follows this line--
I have been told that gcc generated code sometimes runs slower than cc
generated code, in spite of its "better quality and smaller size".

The problems seems to be that the tr registers are faster than other
register categories on the MIServers, and that gcc uses these last,
and cc uses them first.

Fortunately, this is easy to fix.  If anyone is interested, please
contact me by email, and I'll send you the patch needed.
