aab47c049b Fix type of LUXC1 and SUXC1. These instructions were incorrectly defined as 
single-precision load and store.

Also avoid selecting LUXC1 and SUXC1 instructions during isel. It is incorrect
to map unaligned floating point load/store nodes to these instructions.

75b06f4a49 Fix bugs which were introduced when support for base+index floating point loads 
and stores was added.

- SelectAddr should return false if Parent is an unaligned f32 load or store.
- Only aligned load and store nodes should be matched to select reg+imm
  floating point instructions.
- MIPS does not have support for f64 unaligned load or store instructions.
