317201d773 Rename the intrinsic enum values for llvm.va_* from Intrinsic::va_* to 
Intrinsic::va*.  This avoid conflicting with macros in the stdlib.h file.

8709927af8 Fix a bug in the recent rewrite of the leakdetector that caused all of the 
nightly tests to be really messed up.  The problem was that the new leakdetector
was depending on undefined behavior: the order of destruction of static objects.

588e72db75 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.

40bbeb5d07 Add a new ConstantAggregateZero class, to fix PR239. This makes zero 
initializers for constant structs and arrays take constant space, instead of
space proportinal to the number of elements.  This reduces the memory usage of
the LLVM compiler by hundreds of megabytes when compiling some nasty SPEC95
benchmarks.

c3b5849e92 Speed up type resolution some more. On the testcase in PR224, for example, 
this speeds up a release llvm-as from 21.95s to 11.21s, because before it
would do an expensive traversal of the type-graph of every type resolved.

e21f68d1e8 Two problems with these lines of code: 
1. The "work" was not in the assert, so it was punishing the optimized release
 2. getNamedFunction is _very_ expensive in large programs.  It is not designed
    to be used like this, and was taking 7% of the execution time of the code
    generator on perlbmk.

Since the assert "can never fail", I'm just killing it.
