Don't include asm.h in non-asm files.

Remove #define to get kludges that asm.h used to define
Move clever macros to access assembler instructions to trap.c
Remove __ASSEMBLER__ ifdefs in regdef.h: they aren't needed anymore.

* These are temp registers whose names can be used in either the old
* or new ABI, although they map to different physical registers. In
* the old ABI, they map to t4-t7, and in the new ABI, they map to a4-a7.
*
* Because they overlap with the last 4 arg regs in the new ABI, ta0-ta3
* should be used only when we need more than t0-t3.
