9610326d63 Modified the code so that it generates (0) for setjmp() and abort() for 
longjmp() (and does not include setjmp.h).
This is to fix some problems on Sparc while non-local jumps are still
unimplemented.

d4520885a0 When emitting a constant, check for ConstantExpr before 
ordinary (primitive) types since ConstantExprs may be of primitive type!

98618cd85c Add ConvertConstantToIntType() to unify all constant handling 
that depends on machine register size.
Moved insertCallerSavingCode() to PhyRegAlloc and
moved isRegVolatile and modifiedByCall to TargetRegInfo: they are all
machine independent.  Remove several dead functions.

b58f52ab45 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.

9bcbe0c3bc * Correctly emit a far call if the target address does not fit into 30 bits 
instead of assert()ing

442175ec3b * 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.

bugpoint).

c0193ca460 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.
