7bbd6e366b 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.

b4316028b3 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.

a9e37c5eaf 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.

39646d96e7 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).

101771ba4d 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.
