[PATCH] MIPS16 TLS binutils support

[Chung-Lin Tang <cltang at codesourcery dot com>]

Hi Richard,
as aforementioned on gcc-patches, we have MIPS16 TLS implemented, and
here are the binutils parts.

It's mostly straightforward, adding the analogous TLS relocations and
cases for MIPS16. I have also added a .tprel[d]word directive, together
re-arranging the similar code for .dtprel[d]word, which are now used for
laying out offset values in text for MIPS16 pc-relative loading.

I'll be posting the GCC parts later on gcc-patches.

Thanks,
Chung-Lin
