[MIPS, committed] Add tests for MIPS16 and microMIPS PLTs

[Richard Sandiford <rdsandiford at googlemail dot com>]

This patch adds tests for MIPS16 PLT entries, microMIPS PLT entries and
microMIPS lazy-binding stubs.  It's along the lines mentioned in:
http://article.gmane.org/gmane.comp.gnu.binutils/61257

Maciej, you were concerned that this might lose some of your original
testing, so please let me know if I missed something.  We can tweak the
tests or add new ones if necessary.

Tested on the usual targets and applied.

Richard
