New Revision: 99435

URL: http://llvm.org/viewvc/llvm-project?rev=99435&view=rev
Log:
Fixed the SS42AI template for the SSE 4.2 instructions with TA prefix so it does
not get an "Unknown immediate size" assert failure when used.  All instructions 
of this form have an 8-bit immediate.  Also added a test case of an example
instruction that is of this form.
