Instead of processing relocation for branch to stubs right away, emit a
modified relocation and add it to queue to be resolved later when final load
address is known.
This resolves seven MIPS MCJIT issues that were caused by missing relocation
fixups at the end.

Two of the tests are new test cases (cross-module-a.ll, multi-module-a.ll)
not yet supported on MIPS, while XFAIL for the other two tests was
accidentally removed in r193570 and this change reverts those lines.

- Mark tests as XFAIL:cygming in test/ExecutionEngine/MCJIT/remote.
Rather to suppress them, I'd like to leave them running as XFAIL.
- Revert r193472. RecordMemoryManager no longer resolves __main on cygming.
There are a couple of issues.
- X86 Codegen emits "call __main" in @main for targeting cygming.
It is useless in JIT. FYI, tests are passing when emitting __main is disabled.
- Current remote JIT does not resolve any symbols in child context.
FIXME: __main should be disabled, or remote JIT should resolve __main.

At this time only Unix-based systems are supported. Windows has stubs and should re-route to the simulated mode.

Previously we would read-modify-write the target bits when processing
relocations for the MCJIT. This had the problem that when relocations
were processed multiple times for the same object file (as they can
be), the result is not idempotent and the values became corrupted.
The solution to this is to take any bits used in the destination from
the pristine object file as LLVM emitted it.
This should fix PR16013 and remote MCJIT on ARM ELF targets.
