Thanks to NAKAMURA Takumi for noticing it.

Now if we can transform an alloca into a single vector value, but it has
subvector, non-element accesses, we form the appropriate shufflevectors
to allow SROA to proceed. This fixes PR14055 which pointed out a very
common pattern that SROA couldn't handle -- mixed vec3 and vec4
operations on a single alloca.

Mark ISD::FMA as Legal instead of custom for x86 with FMA3/FMA4. Needed so that llvm.muladd can be converted to ISD::FMA for fp_contract.

No semantic change intended.

Before this fix, the LLVM Python bindings on SVN trunk always fail with:
	Exception: LLVM shared library not found!
since it's still looking for a library named "LLVM-3.1svn".

Besides updating the LLVM version in the library name,
this patch also changes llvm.get_library() to make it possible to run
the unit tests without installing the LLVM shared library into a
default linker search path.

e.g. after this patch, running the llvm/python unit tests with:
LD_LIBRARY_PATH=../build/Debug+Asserts/lib nosetests -v bindings/python/llvm/tests/
would work on Linux.
