73bc2c29a8 Fix a couple of slips that can cause crashes 
'Type' is a string with a LSL type. 'Kind' is a single leter denoting the kind of identifier. We meant Kind. Twice.

To follow the standard, hexadecimal and octal values that don't fit an intmax_t must be of type uintmax_t, regardless of the presence of the U suffix.

36ed90c9ba Revert _Pragma operator 
Revert "Add support for C11-style _Pragma operator on processpre".
Revert "Add unit test for the _Pragma operator".

This reverts commits 31fcb331c7 and e261ac2121.

This should rather be the job of the preprocessor, which should generate #pragma lines. gcc does that.

173a12be15 New feature: add preprocessor params before or after system's 
Reverts f958b1cdf9, and adds the possibility of adding parameters after the system-inserted ones through a new command line parameter -A/--postarg.

Enables using e.g. both a command interpreter which requires the file to execute before any other parameters, and overriding the default definitions.

31fcb331c7 Add support for C11-style _Pragma operator on processpre 
A minor difference is that strings and whitespace are parsed according to LSL rules, not to C rules, since this processing is performed in the lexer.

This could be fixed, but is it worth the trouble?

c0168c8a34 Add files necessary to add an internal preprocessor (not implemented yet) 
Includes PCPP as a submodule (which in turn pulls PLY as a submodule, so be sure to initialize submodules recursively). Also includes a file to interface PCPP with the optimizer, patching its behaviour according to our needs.

Special thanks to Niall Douglas and David Bezley for authoring PCPP.

5bfb218505 Perform redundant jump elimination in lastpass 
This is a first try at redundant jump removal (jumps that target the very next instruction). It's too basic in several ways.

- The statement is replaced by a ';' instead of removed.
- If the jump was the only statement in an if, when the if becomes empty, it's not folded.
- Jumps that are last in the 'then' branch of if+else are not visible. This would need either to track multiple last statements, or to have some means to anticipate what the next statement is at every statement. A Control Flow Graph would help a lot.
- When a label is immediately followed by a jump, all jumps to that label should target the destination of that jump if it's in scope. Added to TODO.
- It misses some optimizations when not expanding WHILE and FOR into IF/JUMP.

Moving everything to an earlier stage would help with some of these, especially with ';' and 'if' folding. Unconditionally expanding WHILE and FOR would also help.
