8b31f95bdd Simplify some NEON assembly pseudo definitions. 
Let the generic token alias definitions handle the data subtype
suffices. We don't need explicit versions for each.

51222d1551 NEON use vmov.i32 to splat some f32 values into vectors. 
For bit patterns that aren't representable using the 8-bit floating point
representation for vmov.f32, but are representable via vmov.i32, treat
the .f32 syntax as an alias. Most importantly, this covers the case
'vmov.f32 Vd, #0.0'.

8b9300b972 MC tweak symbol difference resolution for non-local symbols. 
When the non-local symbol in the expression is in the same fragment
as the second symbol, the assembler can still evaluate the expression
without needing a relocation.

For example, on ARM:
_foo:
	ldr lr, (_foo - 4)

8704b7897d The error check for using -g with a .s file already containing dwarf .file 
directives was in the wrong place and getting triggered incorectly with a
cpp .file directive.  This change fixes that and adds a test case.

38fdb7d9fc Various crash reporting tools have a problem with the dwarf generated for 
assembly source when it generates the TAG_subprogram dwarf debug info for
the labels that have nothing between them as in this bit of assembly source:

% cat ZeroLength.s 
_func1:
_func2:
 nop

One solution would be to not emit the subsequent labels with the same address
and use the next label with a different address or the end of the section for
the AT_high_pc value of the TAG_subprogram.

Turns out in llvm-mc it is not possible in all cases to determine of two
symbols have the same value at the point we put out the TAG_subprogram dwarf
debug info.

So we will have llvm-mc instead of putting out TAG_subprogram's put out
DW_TAG_label's.  And the DW_TAG_label does not have a AT_high_pc value which
avoids the problem.

This commit is only the functional change to make the diffs clear as to what is
really being changed.  The next commit will be to clean up the names of such
things like MCGenDwarfSubprogramEntry to something like MCGenDwarfLabelEntry.

99b4237c16 Split Finish into Finish and FinishImpl to have a common place to do end of
