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

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

the "make dist" from the list of targets attempted.

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).
