15369d0b89 Darwin ABI issues: weak, linkonce, etc. dynamic-no-pic support is complete. 
Also fixed a function stub bug. Added weak and linkonce support for
x86 Linux.

080996281c - Update load folding checks to match those auto-generated by tblgen. 
- Manually select SDOperand's returned by TryFoldLoad which make up the
  load address.

This patch speeds up 172.mgrid from 31.81s to 11.39s on darwin/ppc.
Many many thanks to Nate for tracking down the root cause of the issue.

6a366c5eda Complex pattern's custom matcher should not call Select() on any operands.

0ddab3fc99 Custom lower VAARG for the case when we are doing vaarg(double). In this 
case, the double being loaded may not be 8-byte aligned, so we have to use
our standard bit_convert game.

3b39e70a72 Two changes: 
1. Treat FMOVD as a copy instruction, to help with coallescing in V9 mode
2. When in V9 mode, insert FMOVD instead of FpMOVD instructions, as we don't
   ever rewrite FpMOVD instructions into FMOVS instructions, thus we just end
   up with commented out copies!
This should fix a bunch of failures in V9 mode on sparc.
