0d06582cd5 Support for generating ELF objects on Windows. 
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.

037348ce80 MachO: direct-to-object attribute for data-in-code markers. 
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
direct-to-object.

56415ad3cd Provide a shortcut for MCObjectStreamer when emitting fills.

6cba50cbb4 Replaced ReInitMCSubtargetInfo with InitMCProcessor. 
Now where we used to call ReInitMCSubtargetInfo, we actually recompute
the same information as InitMCSubtargetInfo instead of only setting
the feature bits.

93c7ec80b7 Fix Doxygen issues: 
* wrap code blocks in \code ... \endcode;
* refer to parameter names in paragraphs correctly (\arg is not what most
  people want -- it starts a new paragraph);
* use \param instead of \arg to document parameters in order to be consistent
  with the rest of the codebase.

.set a, b - c + CONSTANT

1e7f74aaa8 Add MCRI::getNumSubRegIndices() and start checking SubRegIndex ranges. 
Apparently, NumSubRegIndices was completely unused before. Adjust it by
one to include the null subreg index, just like getNumRegs() includes
the null register.

f7e00de5d0 Fix alignment of .comm and .lcomm on mingw32. 
For some reason .lcomm uses byte alignment and .comm log2 alignment so we can't
use the same setting for both. Fix this by reintroducing the LCOMM enum.
I verified this against mingw's gcc.

f7fdee3ce3 MC: Overhaul handling of .lcomm 
- Darwin lied about not supporting .lcomm and turned it into zerofill in the
  asm parser. Push the zerofill-conversion down into macho-specific code.
- This makes the tri-state LCOMMType enum superfluous, there are no targets
  without .lcomm.
- Do proper error reporting when trying to use .lcomm with alignment on a target
  that doesn't support it.
- .comm and .lcomm alignment was parsed in bytes on COFF, should be power of 2.
- Fixes PR13755 (.lcomm crashes on ELF).

1b099ac7c7 For mips64 switch statements in subroutines could generate 
within the codegen EK_GPRel64BlockAddress. This was not 
supported for direct object output and resulted in an assertion.

This change adds support for EK_GPRel64BlockAddress for 
direct object.

One fallout from this is to turn on rela relocations 
for mips64 to match gas.
