Andrius Štikonas 185ef7a7c2 Improve handling of compound assignment operators. 
Previously, compound assignment operators were replaced in preprocessor.
This only worked for simple cases where we only had 1-token variable.

This commit switches to proper implementation in the parser.

This reverts commit ab49bcafa4.

Andrius Štikonas ab49bcafa4 Add support for pre-increment and pre-decrement operators. 
At the moment there is a limitation on only one unary operator,
so things like *++p wouldn't work but ++*p would work.
