Commit 9666ca3c ("[NFC] Fix sign-compare warnings in math_brute_force
(#1467)", 2022-08-23) inadvertently changed the semantics of the if
condition. The `i > gEndTestNumber` comparison was relying on
`gEndTestNumber` being promoted to unsigned. When casting `i` to
`int32_t`, this promotion no longer happens and as a result any tests
given on the command line were being skipped.
Use an unsigned type for `gStartTestNumber` and `gEndTestNumber` to
eliminate the casts and any implicit conversions between signed and
unsigned types.
