xtensa: fix signedness of gas relocations
Change 1058c7532d0b "Use signed data type for R_XTENSA_DIFF* relocation
offsets." changed signedness of BFD_RELOC_XTENSA_DIFF* relocations
substituted for BFD_RELOC_*. This made it impossible to encode arbitrary
8-, 16- and 32-bit values, which broke e.g. debug info encoding by .loc
directive. Revert this part and add test.

2016-02-03 Max Filippov <jcmvbkbc@gmail.com>
* config/tc-xtensa.c (md_apply_fix): Mark BFD_RELOC_XTENSA_DIFF*
substitutions for BFD_RELOC_* as unsigned.
* gas/testsuite/gas/xtensa/all.exp: Add loc to list of xtensa
tests.
* gas/testsuite/gas/xtensa/loc.d: New file: loc test result
patterns.
* gas/testsuite/gas/xtensa/loc.s: New file: loc test.
