[clang][#52782] Bail on incomplete parameter type in stdcall name mangling
stdcall name mangling requires a suffix with the number equal to the sum of the byte count of all parameter types. In the case of a function prototype that has a parameter type of an incomplete type it is impossible to get the size of the type. While such a function is not callable or able to be defined in the TU, it may still be mangled when generating debug info, which would previously lead to a crash.
This patch fixes that by simply bailing out of the loop and using the so far accumulated byte count. This matches GCCs behaviour as well: https://github.com/gcc-mirror/gcc/blob/bc8d6c60137f8bbf173b86ddf31b15d7ba2a33dd/gcc/config/i386/winnt.c#L203
