R600/SI: Initial support for assembler and inline assembly

This is currently considered experimental, but most of the more
commonly used instructions should work.

So far only SI has been extensively tested, CI and VI probably work too,
but may be buggy.  The current set of tests cases do not give complete
coverage, but I think it is sufficient for an experimental assembler.

See the documentation in R600Usage for more information.

+MUBUF Instructions
+------------------
+All non-atomic MUBUF instructions are supported.

+Only the s_load_dword* SMRD instructions are supported.

 SOPP Instructions

-accept a integer operand(s) only.  No verification is performed on the
-operands, so it is up to the programmer to be familiar with the range
-or acceptable values.

+VOP1, VOP2, VOP3, VOPC Instructions
+-----------------------------------
+
+All 32-bit and 64-bit encodings should work.
+
+The assembler will automatically detect which encoding size to use for
+VOP1, VOP2, and VOPC instructions based on the operands.  If you want to force
+a specific encoding size, you can add an _e32 (for 32-bit encoding) or
+_e64 (for 64-bit encoding) suffix to the instruction.  Most, but not all
+instructions support an explicit suffix.  These are all valid assembly
