[PATCH] [IAS] Support '.word foo-.' on targets that permit this (e.g. Mips).

This is necessary to support DW_EH_PE_pcrel encoded TType references in the
exception handling LSDA on Mips.
Previously for Mips, IAS would emit an R_MIPS_32 relocation given
'.word foo-.' making it functionally equivalent to '.word foo'. It now
emits a R_MIPS_PC32 relocation. Despite the name, R_MIPS_PC32 has
historically been used on data sections and the 'PC' in this context is
the address of the data being fixed up.
