Allow optionally generating pubnames section in DWARF info.  Introduce
option "generate-dwarf-pubnames" to control it, set to "false" by default.

[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.

When disabling PRE for a value is directly redundant with itself

predecessors.

[ms-inline-asm] Implement align directive (which is roughly equivalent to .align).

Also, allow _EMIT and __EMIT for the emit directive.  We already do the same

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.
