optimized `ProgramMemory` a bit (#5668)
Scanning `common/file.c` of the `xrdp` project with `--force --std=c11
--std=c++11 --inline-suppr --enable=warning`:

Clang 16 `4,208,373,435` -> `4,156,024,955`
GCC 13 `4,336,042,153` -> `4,277,293,971`

Set the lower and upper bounds for variable that are only incremented or decremented (#5523)
Also, changed `isExpressionChanged` and `isThisChanged` to return the
token that is being modified and renamed the functions to
`findExpressionChanged` and `findThisChanged`.

MathLib: renamed `to{U}LongNumber()` to `toBig{U}Number()` (#5503)
The name was misleading as it was actually a `long long` and also if we
ever move to an (optional) 128-bit value it wouldn't even less fitting.
We should name it to match our alias type.
