MIPS/GAS: Correct BFD_RELOC_MIPS_18_PCREL_S3 calculation
The PC-relative R_MIPS_PC18_S3 relocation and consequently its BFD
internal BFD_RELOC_MIPS_18_PCREL_S3 representation is calculated from
the address of the aligned doubleword containing the location being
relocated: (sign_extend(A) + S - (P & ~0x7)) >> 3 rather than the
address of the location itself. Reflect this in calculations made by
GAS so that the relocated field is set correctly if resolved by GAS,
such as with local symbols in the same section which do not require
relocations to be propagated to the link stage.

* config/tc-mips.c (md_pcrel_from) <BFD_RELOC_MIPS_18_PCREL_S3>:
Calculate relocation from the containing aligned doubleword.
(tc_gen_reloc) <BFD_RELOC_MIPS_18_PCREL_S3>: Calculate the
addend from the containing aligned doubleword.
