[PATCH] Support for MIPS16 HI16/LO16 relocations

[Eric Christopher]

I'm getting two new failures in the mips64-elf gas testsuite:

FAIL: MIPS16 lui/addi
FAIL: MIPS16 lui/addi n32

with a bfd assertion failure of:

BFD: BFD 2.15.94 20050214 assertion
fail /dzur/sourceware/binutils/src/bfd/elf32-mips.c:1140

and

BFD: BFD 2.15.94 20050214 assertion
fail /dzur/sourceware/binutils/src/bfd/elfn32-mips.c:1697

respectively.
