Daniel Sanders 2e9f69d933 [mips] Range check simm9 and fix a bug this revealed. 
Summary:
The bug was that microMIPS's [ls]w[lr]e instructions claimed to support a
12-bit offset when it is only 9-bit.

Daniel Sanders e57d866ed0 [mips] Marked up instructions added in MIPS-IV and tested that IAS for -mcpu=mips[123] does not accept them 
Summary:
This required a new instruction group representing the 32-bit subset of
MIPS-IV that was available in MIPS32

A small number of instructions are correctly rejected but with the wrong error
message. These have been placed in a separate test for now.

Depends on D3676
