by the back-end to do name lookup in Sema.  Finally, remove the now defunct

However, in the near future I expect these to be sunk back into the MC layer
and more basic APIs (e.g., getClobbers(), getConstraints(), etc.) will be called
by clang.

This patch replaces the EmitRawText by a EmitTCEntry class (specialized for

the interface between the front-end and the MC layer when parsing inline
assembly.  Unfortunately, this is too deep into the parsing stack. Specifically,
we're unable to handle target-independent assembly (i.e., assembly directives,
labels, etc.).  Note the MatchAndEmitInstruction() isn't the correct
abstraction either.  I'll be exposing target-independent hooks shortly, so this
is really just a cleanup.

This adds 'elf' as a recognized target triple environment value and overrides the default generated object format on Windows platforms if that value is present.  This patch also enables MCJIT tests on Windows using the new environment value.

The target backend can support data-in-code load commands even when
the assembler doesn't, or vice-versa. Allow targets to opt-in for

Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.
