  Log Message:
  -----------
  [clang] Fix a crash when passing a C structure of incompatible type to a function with a reference parameter.

__builtin_va_*() and __builtin_ms_va_*() are declared as functions with a
parameter of reference type.

This patch fixes a crash when using these functions in C where an argument
of structure type is incompatible with the parameter type.
