Uppercase condition codes

[Paul Brook]

The parset for the thumb-2 IT instruction currently only accepts lowercase 
condition codes. Patch below makes it case insensitive, like the rest of the 
assembly syntax.  When condition codes are used as part of an opcode the 
string has already been converted to lower case, so this problem does not 
occur.

Tested on arm-eabi.
Applied to cvs HEAD.
