sh-dis/c/decode_execute.c
Zack Buhman ea3c389944 add non-FPU/UBC/MMU/cache SH4 instructions 
Previously, ast transformations were performed informally as ad-hoc
modifications to the generated C source code. In this commit, the
same transformations are performed by rewriting the ast prior to code
generation time.

The most significant new transformer is transform_assignment_list.
This transforms assignments such as:

  a, b, c = f(b, c, d)

To:

  a = f(&b, &c, d)

The former syntax is used frequently in the manual's description of
FPU-related instructions.
