08c429f22b Add IfElseSwap option
This enables an option that was being done unconditionally: to swap the `if` and `else` branches if the condition is shorter when negated.

Enabled by default.

e62b5ffcb6 Fix exception when a global references another without constfold
Fixes #19. Thanks to SaladDais for the report and test case.

With constant folding inactive, the dead code removal optimization was removing globals and their symbols when they were e.g. integer constants, without substituting them in other globals. This produced a crash when the output module tried to access said symbols.

For example, in this code:

```
integer A = 1;
integer B = A;
default{timer(){llBreakLink(B);}}
```

the line `integer A = 1` was being removed, as well as the `A` global symbol, but the line `integer B = A` was retained with the missing symbol, and the output module crashed when trying to look up the `A` symbol.

Apparently, it wasn't an issue when constant folding was active (which is why it went unnoticed for so long) because the constant folding code sets 'orig' in the symbol table to the original value the variable was being set to, which let the output module know what to output.

The fix is to replace the references to deleted symbols with their values in global definitions. In normal code that was already happening.

bc992e6182 LL change: the status of STATUS_DIE_AT_* is returned
As of Second Life Server 2022-09-09.574921, STATUS_DIE_AT_EDGE and STATUS_DIE_AT_NO_ENTRY return their corresponding settings rather than always FALSE.

Regression/coverage tests are clearly lacking in this area, as the change didn't trigger any test breakage, therefore add some unit tests.

7eaa4cb0ad Fix --postarg and add option --preproc-show-cmdline + unit test
Thanks to @Blues-Today for reporting that --postarg was not working.

This needed a regression test, and the best way to distinguish --prearg from --postarg is to display the full preprocessor command line, therefore a new option was added for that purpose: --preproc-show-cmdline

Fixes #18.

d2e64e25a6 Rewrite Mono float to string conversion; fix llDumpList2String
llDumpList2String has changed its behaviour with respect to minus zero. Now it converts -0.0 to a string without the minus sign.

While testing this, we noticed several mismatches in the float to string conversions; the existing routine did not properly convert some values because as we discovered later, it is subject to double rounding; one of them is the built-in round-to-nearest-or-even while getting the first 7 significant digits, and the other is just an increment when the digit is a 5 or more, so round to nearest, ties away from zero, and is performed on the digit past the five or six visible digits that LSL shows.

The new code is a tad easier to understand and more robust.

A first variant of the new code is left commented out for history's sake, and will be removed in the next commit.

281ff4d96a Strings representing denormals no longer give 0 when cast to float
This annoyance and discrepancy with LSO was finally fixed by Linden Lab. The change has prompted some modifications to the test suite to accommodate for the new results. A further improvement has been to make these tests more friendly to be run in SL, making it easier to verify the results.

Fixes #17.

bf72d2c3bf Allow //pragma inline or /*pragma inline*/ for inlining a function
They are transformed by the scanner to the identifier `inline`, which is how the parser identifies it. This solves the comment problem, but it results in a funny side effect. Now, in inline mode, /*pragma inline*/ will always be the identifier `inline`, therefore this is valid:

    integer /*pragma inline*/ = 5;
    llOwnerSay((string)inline); // will say 5

Not overly elegant, but better than making up a specific token or declaring comments as tokens or the like.

It's unlikely to hit this one (requires more than 10,000 identifiers to trigger) but it's a bug nevertheless.

5e88adcff3 Update to latest pcpp, remove expression evaluator
PCPP now includes a decent expression evaluator instead of relying on Python's, therefore our evaluator is removed. The corresponding license text no longer applies, because the snippet that used it has been removed.

This patch also corrects the handling of include files, which was supposed to raise an exception or return something (and now it needs an extra parameter). We just report an error and raise the special exception that pcpp uses to ignore and remove the directive.

This patch also handles #error and invalid directives, which were passed through in previous versions. #warning and #line are also passed through.

8db8872dbe Import the changes to cpreproc.py from the preprocessor branch
These changes make it ready for prime time, but main.py still does not expose the functionality.

Changes include:

- Instead of passing paths, we pass parameters, which are parsed to extract the paths (no syspaths, only regular paths) and the defines.
- Errors in the preprocessor are reported to the caller (i.e. to main).
