No functional change.

b33e5e07e1 Change some methods in MCDwarf.cpp to be able to handle an arbitrary 
MCStreamer instead of just MCObjectStreamer. Address changes cannot
be as efficient as we have to use DW_LNE_set_addres, but at least
most of the logic is shared.

This will be used so that, with CodeGen still using EmitDwarfLocDirective,
llvm-gcc is able to produce debug_line sections without needing an
assembler that supports .loc.

50a1812023 Add MC encodings for some Thumb instructions. Test for a few of them. The "bx 
lr" instruction cannot be tested just yet. It requires matching a "condition
code", but adding one of those makes things go south quickly...

331b7407c8 Fix .o emission of ARM movt/movw. MCSymbolRefExpr::VK_ARM_(HI||LO)16 for the .o path now works for ARM. 
Note: lo16AllZero remains in ARMInstrInfo.td - It can be factored out when Thumb movt is repaired.
Existing tests cover this update.

510e600542 Don't allocate the SmallVector of Registers. It gets messy figuring out who 
should delete what when the object gets copied around. It's also making valgrind
upset.

2ada679434 Split up ARM LowerShift function. 
This function was being called from two different places for completely
unrelated reasons.  During type legalization, it was called to expand 64-bit
shift operations.  During operation legalization, it was called to handle
Neon vector shifts.  The vector shift code was not written to check for
illegal types, since it was assumed to be only called after type legalization.
Fixed this by splitting off the 64-bit shift expansion into a separate
function.  I don't have a particular testcase for this; I just noticed it
by inspection.

c85f76f7da trivial QoI improvement. On this invalid input: 
sahf	movl	344(%rdi),%r14d
we used to produce:

t.s:2:1: error: unexpected token in argument list

^

we now produce:
t.s:1:11: error: unexpected token in argument list
sahf	movl	344(%rdi),%r14d
    	    	^

93a07b464e Change CodeGen to use .loc directives. This produces a lot more readable output 
and testing is easier.  A good example is the unknown-location.ll test that
now can just look for ".loc 1 0 0".  We also don't use a DW_LNE_set_address for
every address change anymore.
