Describe the bug

Attempting to use comparison operators like < throws an error in a cudaq.kernel.

Steps to reproduce the bug

@cudaq.kernel
def test_kernel():
    a = 0.5 < 1.0

Will throw:

error: 'arith.cmpi' op operand #0 must be signless-integer-like, but got 'f64'
RuntimeError: Failure while executing pass pipeline.

During handling of the above exception, another exception occurred:

RuntimeError: could not compile code for 'test_kernel'.

Expected behavior

Comparison operators should function for floats.

Is this a regression? If it is, put the last known working version (or commit) here.

Not a regression
