gas-980313 mips64orion problems

[Joel Sherrill <joel@OARcorp.com>]

The same mips64orion problem which existed in gas-980310 still
exists in gas-980313.

If I am reading diffs-weekly-980310 correctly, then a chunk of
code in tc-mips.c was deleted.  My guess is that the mips gas is broken on
just about every configuration right now.

I readded the code deleted by the change in diffs-weekly-980310 and
this allowed tc-mips.c to compile but later the build failed trying
to build egcs-1.0.2-980309-prerelease with the following:
