<pre>The function RuntimeDyldELF::resolveX86_64Relocation() contains code similar to
the following code pattern
uint64_t *Target = reinterpret_cast<uint64_t*>(Section.Address + Offset);
*Target = Value + Addend;
Since the pointer "Target" is not guaranteed to be 64 bit aligned, it causes
bus error in Sparc.
This causes the following unit cases to fail in SPARC.

LLVM :: MC/COFF/seh-align2.s
LLVM :: MC/COFF/seh-align3.s</pre>
