db68577691 When emitting a constant, check for ConstantExpr before 
ordinary (primitive) types since ConstantExprs may be of primitive type!

moved isRegVolatile and modifiedByCall to TargetRegInfo: they are all
machine independent.  Remove several dead functions.

814030a0c5 1. Bug fix: Don't use branch operand reg. as temp. reg. when 
spilling values used by an instruction in the delay slot of the branch
   (which will eventually be moved before the branch).
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.

89e8be00c5 * Stop hard-coding a value for beginning of emitted code on Sparc since we can 
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.

d69c1e6dc2 Add ability for external C code to get pointers to functions given their name. 
This us used by bugpoint -- when code is compiled to a shared object to be
JITted, it must use the JIT's lazy resolution method to find function addresses,
because some functions will not be available at .so load time, as they are in
the bytecode file.

7dc7de5391 (1) Major fix to the way unused regs. are marked and found for the FP 
Single and FP double reg types (which share the same reg class).
    Now all methods marking/finding unused regs consider the regType
    within the reg class, and SparcFloatRegClass specializes this code.
(2) Remove machine-specific regalloc. methods that are no longer needed.
    In particular, arguments and return value from a call do not need
    machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
    overloading when an include file is omitted.
