[ConstraintElimination] Rewrite tests to reduce verification complexity.
...
This patch reduces the bitwidth of types certain tests operate and gets
rid of a number of @use(i1) calls and xor's the conditions together
instead, which eliminates all timeouts when verifying the tests.
See https://github.com/AliveToolkit/alive2/issues/744 for more details.

During decomposition, we assume the no-wrap properties of inbound GEPs.
Make sure the decomposed GEP is actually inbounds.

[ConstraintElimination] Extend test coverage.
...
This patch adds a lot of additional tests, focusing on loops and GEP
arithmetic. Some of the tests expose existing problems, which will be
fixed soon.
