On Mips32r2 bitcast can be expanded to two sw instructions and an ldc1 when using bitcast i64 to double or an sdc1 and two lw instructions when using bitcast double to i64. By introducing custom lowering that uses mtc1/mthc1 we can avoid excessive instructions. Patch by Mirko Brkusanin. Differential Revision: https://reviews.llvm.org/D61069 llvm-svn: 359171
