Chris Lattner 956820d989 Nate noticed that 30% of the malloc/frees in llc come from calls to LowercaseString ...

in the asmprinter.  This changes the .td files to use lower case register names,
avoiding the need to do this call.  This speeds up the asmprinter from 1.52s
to 1.06s on kc++ in a release build.
