Vasileios Kalintiris d72ba1af57 [mips] Optimize code generation for 64-bit variable shift instructions. 
Summary:
The 64-bit version of the variable shift instructions uses the
shift_rotate_reg class which uses a GPR32Opnd to specify the variable
shift amount. With this patch we avoid the generation of a redundant
SLL instruction for the variable shift instructions in 64-bit targets.
