Add -Wno-nested-anon-types to -pedantic builds of LLVM. This Clang warning
catches uses of an extremely minor and widely-available C++ extension (which
every C++ compiler I could find supports, but EDG and Clang reject in strict
mode).
The diagnosed code pattern looks like this:
struct X {
union {
struct {
int a;
int b;
} S;
};
};
