Fix the check for regparm in FunctionType::ExtInfo `getHasRegParm()` was working under the assumption that the RegParm bits are the last field, which is no longer true, after adding the `NoCfCheck` and `CmseNSCall` fields. This causes a spurious "regparm 0" attribute to appear when a function type is declared with either `__attribute__((nocf_check))` or `__attribute__((cmse_nonsecure_call))`.
