f4f4ce1e3c Default OPTIMIZE_OPTION to -O2 on FreeBSD, at the request of the Clang/FreeBSD 
folks. LLVM/Clang is miscompiled by the standard GCC at -O3.

e59c44ea79 Make sure SmallBitVector actually uses the small case and fix latent bugs. 
- We can't use PointerIntPair here since we require the discrimination bit to be in the LSB.

01254ea96d Reject really weird coalescer case when trying to merge identical subregisters 
of different register classes. e.g.

  %reg1048:3<def> = EXTRACT_SUBREG %RAX<kill>, 3

Where %reg1048 is a GR32 register. This is not impossible to handle, but it is
pretty hard and very rare.

This should unbreak the dragonegg builder.

36cfc45cf3 Verify metadata harder. In particular, check that module 
level metadata does not have any function local operands.
This would have caught the problem found in PR6112.

9ddbae859f Fix PR6910. 
Limit alignment in SmallVector 8, otherwise GCC assumes 16 byte alignment.
opetaror new, and malloc only return 8-byte aligned memory on 32-bit Linux,
which cause a crash if code is compiled with -O3 (or -ftree-vectorize) and some
SmallVector code is vectorized.
