Bug 24029 – ImportC: symbol name clash on statement expressions

Found in the test case of https://github.com/dlang/dmd/pull/15375 with multiple asserts. Reduced: ```C int x = 0; int y = 0; void a() { (__extension__ ({ x += 2; })); // test.a.__dgliteral1 } void b() { (__extension__ ({ y += 1; })); // test.b.__dgliteral1 } int main(void) { a(); b(); __check(x == 2); __check(y == 1); return 0; } ``` Output: ``` /usr/bin/ld: warning: size of symbol `__dgliteral1' changed from 20 in test.o to 19 in test.o ``` And the test fails. Because it's ImportC, the __dgliteral symbols don't get their function as a prefix in the mangle, so the symbols clash.
