Remove all TARGET_[ARM|X86|MIPS] #ifdefs

Two steps forward, one step back towards elimination of the
"#include" build model for target-specific compilers.  This CL
does some restructuring to eliminate all of the TARGET_xxx #ifdefs
and convert them to run-time tests.

Considerable work is still required to fully eliminate the multiple
builds.  In particular, much of the "common" codegen code relies on
macros defined by the target-specific [Arm|X86|Mips]Lir.h include file.

Next step is more restructuring to better isolate target-independent
code generation code.
