a4e0020e54 Add support to the local allocator for fusing spill code into the instructions 
that need them.  This is very useful on CISCy targets like the X86 because it
reduces the total spill pressure, and makes better use of it's (large)
instruction set.  Though the X86 backend doesn't know how to rewrite many
instructions yet, this already makes a substantial difference on 176.gcc for
example:

Before:
Time:
   8.0099 ( 31.2%)   0.0100 ( 12.5%)   8.0199 ( 31.2%)   7.7186 ( 30.0%)  Local Register Allocator

Code quality:
734559 asm-printer           - Number of machine instrs printed
111395 ra-local              - Number of registers reloaded
 79902 ra-local              - Number of registers spilled
231554 x86-peephole          - Number of peephole optimization performed

After:
Time:
   7.8700 ( 30.6%)   0.0099 ( 19.9%)   7.8800 ( 30.6%)   7.7892 ( 30.2%)  Local Register Allocator
Code quality:
733083 asm-printer           - Number of machine instrs printed
  2379 ra-local              - Number of reloads fused into instructions
109046 ra-local              - Number of registers reloaded
 79881 ra-local              - Number of registers spilled
230658 x86-peephole          - Number of peephole optimization performed

So by fusing 2300 instructions, we reduced the  static number of instructions
by 1500, and reduces the number of peepholes (and thus the work) by about 900.
This also clearly reduces the number of reload/spill instructions that are
emitted.

336c99d138 Now that the lowerinvoke pass inserts calls to llvm.setjmp/llvm.longjmp, some 
hacks can be banished.  Also, this gives us the opportunity to emit special code
for the setjmp/longjmps which alows the elimination of one GCC warning for every
setjmp/longjmp site (which is often THOUSANDS in C++ programs).  Yaay!

ded1ad2846 Refactor code. Now the intrinsic lowering pass tries to recycle preexisting 
prototypes, even if they don't precisely match what it would prefer to use.
This fixes: CBackend/2004-02-15-PreexistingExternals.llx compiling it into:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_30 = memcpy(((int *)l27_A), ((unsigned )(long)l27_B), ((int )123u));

instead of:

  ltmp_0_30 = memcpy(l14_C, 4u, 17);
  ltmp_1_27 = l43_memcpy(l27_A, l27_B, 123u);

Which does the wrong thing as you could imagine.

81155b0069 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or 
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

fbacee0077 Add support for fopen/fclose. Specifically with fopen, we were marking all of the 
operands as incomplete, though fopen is known to only read them.  This just adds
fclose for symmetry, though it doesn't gain anything.  This makes the dsgraphs for
181.mcf much more precise.
