Rework the alignment check for BFD_RELOC_MIPS_18_PCREL_S3.
gas/ * config/tc-mips.c (md_apply_fix): Apply alignment check to the symbol and offset rather than *valP for BFD_RELOC_MIPS_18_PCREL_S3. Also update the error message for BFD_RELOC_MIPS_19_PCREL_S2. gas/testsuite/ * gas/mips/r6-64.s: Remove .align directives from LDPC instructions and add further tests for LDPC. * gas/mips/r6-64-n32.d: remove the NOPs from LDPC expected output and update for new tests. * gas/mips/r6-64-n64.d: Likewise. * gas/mips/ldpc-unalign.l: New file. * gas/mips/ldpc-unalign.s: Likewise. * gas/mips/mips.exp: Run ldpc-unalign test.
