Improve siphash performance for small keys by up to 30% (#3124) 
This removes the partial buffer handling from the full slice api.

`./benchmark --filter siphash --count 1024`

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.

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

```zig
const Foo = struct {
    field: Bar(@alignOf(*Foo)),
};
fn Bar(comptime alignment: u29) type {
    return struct {
        field: *align(alignment) Foo,
    };
}

a610352271 std/hash: Revert crc32 api change 
This is user specified and the user doesn't necessarily have to use one
of the provided polynomials declared hence we can't use an enum.

Thanks @daurnimator for catching this.

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.

16fa255f48 Inline full slice hashing 
This gives moderate speed improvements when hashing small keys.
The crc/adler/fnv inlining did not provide enough speed up to warrant
