Added classes SolarisTargetInfo and

SolarisSparcV8TargetInfo to be able
to handle "sparc-" triple prefixes.

Please be aware that this is a minimal
kludge, that pretty much duplicates
the features of DarwinPowerPCTargetInfo,
and also incorrectly uses stuff from
the PPC namespace.

But in result "make test" now passes
a lot of tests, the notable exceptions
being the objc rewrite tests and
mandel.c.
