NAKAMURA Takumi c3e48c38bf Dwarf: [PR11022] Fix emitting DW_AT_const_value(>i64), to be host-endian-neutral.
Don't assume APInt::getRawData() would hold target-aware endianness nor host-compliant endianness. rawdata[0] holds most lower i64, even on big endian host.

FIXME: Add a testcase for big endian target.

FIXME: Ditto on CompileUnit::addConstantFPValue() ?
