Reduce the chance of accidentally calling functions in CTFE
...
previously miri had a check for const fn and other cases that
CTFE requires. Instead the function call is completely
processed inside the machine. This allows CTFE to have full
control over what is called and miri to not have useless
CTFE-checks in normal mode.
