Add the llvm-config directory to the EXTRA_DIST line so it gets distributed
even though its not being built currently. This prevents dist-check from
failing because configure can't find llvm-config.in.in

Make sure that the C Frontend's runtime library directory is included as
a -L option to gccld whenever we're building a bytecode module or archive.
This gets around the "Cannot find library 'crtend'" warning messages.

Turn casts into getelementptr's when possible.  This enables SROA to be more
aggressive in some cases where LLVMGCC 4 is inserting casts for no reason.

This implements InstCombine/cast.ll:test27/28.

Rename get_VSPLI_elt -> get_VSPLTI_elt

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.

Ensure that zero vectors are always v4i32, which forces them to CSE with
each other.  This implements CodeGen/PowerPC/vxor-canonicalize.ll

Make sure both member variables are initialized in the default constructor
for SDOperand. This gets rid of numerous warnings in lib/CodeGen and

Don't memoize vloads in the load map!  Don't memoize them anywhere here, let

Remove extraneous building in target dist-check. There is no reason that
a distribution should need to be able to make a distribution so eliminate
the "make dist" from the list of targets attempted.
