This is to fix some problems on Sparc while non-local jumps are still
unimplemented.

Moved insertCallerSavingCode() to PhyRegAlloc and
moved isRegVolatile and modifiedByCall to TargetRegInfo: they are all
machine independent.  Remove several dead functions.

2. Bug fix:  Delete the delay slot instr, not the branch instr, when
   moving delay slot instr. out!!!!
3. Move code to insert caller-saves moved here from SparcRegInfo:
   it is now machine-independent.

Fix problem with using branch operand reg. as temp. reg. when

  now handle far calls (i.e., beyond the 30-bit limit in call instructions).
* As a side-effect, this allows us to unify and clean up the mmap() call and
  code around it.
