[ARM] 't' asm constraint should accept i32
't' constraint normally only accepts f32 operands, but for VCVT the
operands can be i32. LLVM is overly restrictive and rejects asm like:
float foo() {
float result;
__asm__ __volatile__(
"vcvt.f32.s32 %[result], %[arg1]\n"
: [result]"=t"(result)
: [arg1]"t"(0x01020304) );
return result;
}
Relax the value type for 't' constraint to either f32 or i32.
