4007324b58 Make sure that if anyone passes a name by accident for the isSigned 
parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler).  Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)

to pull Compiler.h into such a public header, but at least Compiler.h
doesn't pull anything else in.
