[analyzer] Fix function macro crash

Description

[analyzer] Fix function macro crash

When there is a functor-like macro which is passed as parameter to another
"function" macro then its parameters are not listed at the place of expansion:

#define foo(x) int bar() { return x; }
#define hello(fvar) fvar(0)
hello(foo)
int main() { 1 / bar(); }

Expansion of hello(foo) asserted Clang, because it expected an l_paren token in
the 3rd line after "foo", since it is a function-like token.
