PATCH [3/4] C-SKY port V3: assembler

[Andrew Jenner <andrew at codesourcery dot com>]

This part of the C-SKY patch set includes the assembler pieces.

Both C-SKY variants have complex/irregular instruction sets with many
different operand types that all need special parsing and error-checking
code.  Particularly for V2, the same syntax may have multiple encodings
which are selected based on register and constant ranges, etc; that's
what the *_work functions are for.

BTW, the literal pool placement code (which is probably the most complex
part of tc-csky.c) looked like it was copied from ARM, which might be a
useful tidbit when reviewing that section.
