3f16e8b729 First step to allowing the resource directory of Clang to be adjusted for 
strange packaging environments. The primary result of this is to expose
a (normally empty) CLANG_RESOURCE_DIR string in the autoconf and CMake builds.
This will in turn be used by a subsequent commit to Clang.

Regenerated configure and config.h.in thanks to Nick. =D

4a85646d6c lib/CodeGen/TargetLoweringObjectFileImpl.cpp: Tweak to emit ".{section}${name}" instead of ".{section}$linkonce_{name}" for linkonce sections. 
It seems GNU ld/PECOFF relies on section names, linking with g++'s libstdc++.a would fail.

9c3f6f486e - Add a hook for target to determine whether an instruction def is 
"long latency" enough to hoist even if it may increase spilling. Reloading
  a value from spill slot is often cheaper than performing an expensive
  computation in the loop. For X86, that means machine LICM will hoist
  SQRT, DIV, etc. ARM will be somewhat aggressive with VFP and NEON
  instructions.
- Enable register pressure aware machine LICM by default.

8a3030c6af Added a few tweaks to the Intel Descriptor-table support instructions to allow 
word forms and suffixed versions to match the darwin assembler in 32-bit and
64-bit modes.  This is again for use just with assembly source for llvm-mc .

cb18d38b76 Added a handful of x86-32 instructions that were missing so that llvm-mc would 
be more complete.  These are only expected to be used by llvm-mc with assembly
source so there is no pattern, [], in the .td files.  Most are being added to
X86InstrInfo.td as Chris suggested and only comments about register uses are
added.  Suggestions welcome on the .td changes as I'm not sure on every detail
of the x86 records.  More missing instructions will be coming.
