f09e02f01a X86: Disable generation of rep;movsl when %esi is used as a base pointer. 
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

Fixes PR15249 and unbreaks firefox on i386/freebsd. Mozilla uses dynamic allocas
and freebsd a 4 byte stack alignment.

4be3853fd0 Debug Info: LiveDebugVarible can remove DBG_VALUEs, make sure we emit them back. 
RegisterCoalescer used to depend on LiveDebugVariable. LDV removes DBG_VALUEs
without emitting them at the end.

We fix this by removing LDV from RegisterCoalescer. Also add an assertion to
make sure we call emitDebugValues if DBG_VALUEs are removed at
runOnMachineFunction.

8915e27704 [ms-inline asm] Add support for lexing binary integers with a [bB] suffix. 
This is complicated by backward labels (e.g., 0b can be both a backward label
and a binary zero).  The current implementation assumes [0-9]b is always a
label and thus it's possible for 0b and 1b to not be interpreted correctly for
ms-style inline assembly.  However, this is relatively simple to fix in the
inline assembly (i.e., drop the [bB]).

This patch also limits backward labels to [0-9]b, so that only 0b and 1b are
ambiguous.

7eacad03ef [NVPTX] Disable vector registers 
Vectors were being manually scalarized by the backend.  Instead,
let the target-independent code do all of the work.  The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

6158ad1bc7 R600: Fix regression with shadow array sampler on pre-SI GPUs. 
'R600/SI: Use proper instructions for array/shadow samplers.' removed two
cases from TEX_SHADOW. Vincent Lejeune reported on IRC that this broke some
shadow array piglit tests with the r600g driver. Reinstating the removed
cases should fix this, and still works with radeonsi as well.

I will follow up with some lit tests which would have caught the regression.

NOTE: This is a candidate for the Mesa stable branch.
