f3e9546fc1 SmallBitVector: Rework find_first/find_next and tweak test to test them (at least on 64 bit platforms).

e4ebf09068 Implement a read/write operator[] for SmallBitVector with a proxy class.

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.

9303b11e47 Another sibcall bug. If caller and callee calling conventions differ, then it's only safe to do a tail call if the results are returned in the same way.

db377e2f86 Fix the OProfileJITEventListener build after r101844 removed 
MachineFunction::DefaultDebugLoc.  We now use the same technique as
DwarfDebug::beginFunction to find the starting line number for a
function.

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.

4137a14e18 - Really preserve dbg_value instructions when the register is spilled. 
- Also, update dbg_value is the value is being re-matted from a frame slot, e.g. fixed slots for arguments.
