[LLVMdev] instruction selection based on size

[reed kotler]

in mips16, we have two versions of many of the instructions that have 
immediate fields.

one version is 16 bits and the other is 32 bits.

we want it to chose the 16 bit version but both patterns will match the 
selection dag if the
immediate fields is small enough.

any simple way to do this?

tia.
