ae43cab6ba Fix known typos
Sweep the codebase for common typos. Includes some changes to visible function
names that were misspelt.

e54c1060a6 [SystemZ] Optimize fcmp X, 0 in cases where X is also negated
In such cases it's often better to test the result of the negation instead,
since the negation also sets CC.

9f9758935a [SystemZ] Use LOAD AND TEST for comparisons with -0
...since it os equivalent to comparison with +0.

29e873ddb6 [SystemZ] Optimize floating-point comparisons with zero
This follows the same lines as the integer code.  In the end it seemed
easier to have a second 4-bit mask in TSFlags to specify the compare-like
CC values.  That eats one more TSFlags bit than adding a CCHasUnordered
would have done, but it feels more concise.
