Required prerequisites

• Consult the security policy. If reporting a security vulnerability, do not report the bug using this form. Use the process described in the policy to report the issue.
• Make sure you've read the documentation. Your issue may be addressed there.
• Search the issue tracker to verify that this hasn't already been reported. +1 or comment there if it has.
• If possible, make a PR with a failing test to give us a starting point to work on!

Describe the bug

It seems the bridge is getting lost when using captured globals. In the following case, angle, seems to be identified as a float; the symbols table's entry, however, has its type as !cc.ptr<f64>, which is not indeed a f64. Thus the issues seems to be that the user of angle expects a value (register), while the bridge symbol table gets populated with memory.

import cudaq

angle = 3.14

@cudaq.kernel
def kernel():
    qubit = cudaq.qubit()
    rz(angle, qubit)
    mz(qubit)

ret = cudaq.sample(kernel)
print(ret)

cudaq.kernel.ast_bridge.CompilerError: bug_me.py:8: error: rotational parameter must be a float, or int.
	 (offending source -> rz(angle, qubit))
