different types.

Codegen spltw(0x7FFFFFFF) and spltw(0x80000000) without a constant pool load,
implementing PowerPC/vec_constants.ll:test1.  This compiles:

typedef float vf __attribute__ ((vector_size (16)));
typedef int vi __attribute__ ((vector_size (16)));
void test(vi *P1, vi *P2, vf *P3) {
  *P1 &= (vi){0x80000000,0x80000000,0x80000000,0x80000000};
  *P2 &= (vi){0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF,0x7FFFFFFF};
  *P3 = vec_abs((vector float)*P3);
}

_test:

        oris r6, r2, 49152
        mtspr 256, r6

instead of (with two constant pool entries):

GCC produces (with 2 cp entries):

_test:
        mfspr r0,256
        stw r0,-4(r1)
        oris r0,r0,0xc00c

even though its not being built currently. This prevents dist-check from
failing because configure can't find llvm-config.in.in

a -L option to gccld whenever we're building a bytecode module or archive.
This gets around the "Cannot find library 'crtend'" warning messages.

Canonicalize BUILD_VECTOR's that match VSPLTI's into a single type for each
form, eliminating a bunch of Pat patterns in the .td file and allowing us to
CSE stuff more aggressively.  This implements
PowerPC/buildvec_canonicalize.ll:VSPLTI

Make this test more interesting by checking that the 0.0 used to implement vector fmul gets cse'd also.

Implement support for the formal_arguments node.  To get this, targets shouldcustom legalize it and remove their XXXTargetLowering::LowerArguments overload

Changed the order of operations so that more of the fine tuning is
performed in the release branch.  This should free up mainline sooner to
resume development.
Removed information on the special release Makefile targets as I've never
used them for a release; Tanya is investigating their integration, and they
can be re-added if she uses them.
Added an outline for building the LLVM GCC binary distributions.  I will
be filling that section out later (but before the 1.7 release).
