eda4d9cb09 Add all arithmetic operators to ConstantExprToString().
Note that some generated operators (like &, | or ^) may
not be supported by the assembler -- but if they've got
this far, it's better to generate them and let the assembler decide.

b68bd55363 *Both* operands of divide need sign-extension before divide (if smaller
than machine register size), not just the second operand.

4576ae1530 Put back the separate pass to decompose multi-dimensional references
since it is *necessary* for correct code generation.  Only optional
transformations belong in the PreOpts pass (which needs to be renamed
from PreSelection to PreOpts).

4449b3c963 I think local symbols in X86 GAS have to start with .L, not just
.; so I have changed the basic block markers to start with .L.  I also
broke up a >80char line.

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.

98618cd85c Add ConvertConstantToIntType() to unify all constant handling

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.

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.

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.
