For support of new GCC v4, obtain the full and major versions of the
llvm-gcc command. This will help distinguish which version is being used
so the makefiles can accommodate.

These intrinsics are now lowered by the FE.

Pattern match vmrg* instructions, which are now lowered by the CFE into shuffles.

Infer element types for shuffle masks

rename a method, to avoid confusion with llvm intrinsics.

test vperm promotion

Lower vperm(x,y, mask) -> shuffle(x,y,mask) if mask is constant.  This allows
us to compile oh-so-realistic stuff like this:

 vec_vperm(A, B, (vector unsigned char){14});

to:
        vspltb v0, v0, 14

instead of:

        vspltisb v0, 14
        vperm v0, v2, v1, v0

this is no longer an intrinsic.

Support pattern matching vsldoi(x,y) and vsldoi(x,x), which allows the f.e. to
lower it and LLVM to have one fewer intrinsic.  This implements
CodeGen/PowerPC/vec_shuffle.ll

Compile the vpkuhum/vpkuwum intrinsics into vpkuhum/vpkuwum instead of into
vperm with a perm mask lvx'd from the constant pool.
