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.

A target that doesn't support these intrinsics will still meet spec (the
...
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.
