1df75da918 remove no longer needed gcc8 workaround. add gcc9 workaround 
Occasionally LLVM headers generate warnings with newer gcc versions and
since we use -Werror this has to be worked around.

ede0c22a67 make @alignOf lazily evaluate the target type 
this case works now:

```zig
const Foo = struct {

};
fn Bar(comptime alignment: u29) type {
    return struct {
        field: *align(alignment) Foo,
    };
}

efdbede7ab breaking: remove field alignment kludge 
This breaks behavior tests as well as compile error notes for generic
function calls. However it introduces better circular dependency compile
errors.

The next step is to add Lazy Values to fix the regressions.

LLVM incorrectly reports 8 as the alignment of i128 on x86_64 but it
correctly reports 16 as the alignment of i128 on aarch64.
