Hi Paul,

The change I am looking at are 2-fold.

1) Replace unnecessary calls to strcmp with memcmp (i.e cases
where string length has already been compared)

2) Remove the `isupper()` branch in STRINGI_HASH. This is just
objectively slower.

The motivation is I'm seeing pretty high CPU usage in hash_find_slot
and `strcmp` when making the GLIBC benchmark suite.
