Log:
Addition of tests to previous check-in. Tests for coprocessor register usage in Sparc.

Previous check-in message was:

The patch adds missing registers and instructions to complete all the registers supported by the Sparc v8 manual.
These are all co-processor registers, with the exception of the floating-point deferred-trap queue register.
Although these will not be lowered automatically by any instructions, it allows the use of co-processor
instructions implemented by inline-assembly.

Code Reviewed at http://reviews.llvm.org/D17133, with the exception of a very small change in brace placement in SparcInstrInfo.td,
which was formerly causing a problem in the disassembly of the %fq register.
