fda6affb95 Autogenerate a table of intrinsic names, so we can map from intrinsic ID to 
LLVM intrinsic function name.

dfdcd5bb95 Set TargetPrefix on target-specific intrinsics. That way, in theory, different 
targets could have different implemenations of a __builtin_foo gcc intrinsic.

'vsetfp', to reflect the fact that the semantics are different for
integer and fp values.

09a053a777 Allow a sequence of digits at the end of the directory name when trying to 
determine the top directory. This allows the tool to find the correct top
directory when you have something like:

   /x/llvm
   /x/llvm2
   /x/llvm3

Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.

1877ec9b02 For functions that use vector registers, save VRSAVE, mark used 
registers, and update it on entry to each function, then restore it on exit.

This compiles:

void func(vfloat *a, vfloat *b, vfloat *c) {
        *a = *b * *c + *c;
}

to this:

_func:
        mfspr r2, 256
        oris r6, r2, 49152
        mtspr 256, r6
        lvx v0, 0, r5
        lvx v1, 0, r4
        vmaddfp v0, v1, v0, v0
        stvx v0, 0, r3
        mtspr 256, r2
        blr

GCC produces this (which has additional stack accesses):

_func:
        mfspr r0,256
        stw r0,-4(r1)
        oris r0,r0,0xc000
        mtspr 256,r0
        lvx v0,0,r5
        lvx v1,0,r4
        lwz r12,-4(r1)
        vmaddfp v0,v0,v1,v0
        stvx v0,0,r3
        mtspr 256,r12
        blr
