[Patch] [MIPS] Change opcode membership of the jalx instruction

[Catherine Moore]

This patch changes the opcode membership of the jalx instruction from 
I16 to I1.  As a result, the use of I16 becomes obsolete along with 
the definitions and uses of INSN_MIPS16.  A new testcase is added and 
an inappropriate testcase is deleted.

Does this look okay to install?

Thanks,
Catherine
