Commit Message

fix: postfix pre-operation slot is a temporary, not a declaration (#300)

Naming the slot `<operand>_pre` and inserting it put a compiler temporary
in the user identifier namespace. insertSymbol reports a collision through
a bool return that was ignored, so lookup handed back the user's own
variable: `int x_pre;` beside `x++` was the same object, and the program
silently computed the wrong answer. At file scope the operand name is
unmangled, so the slot reached code generation as a missing global and
rejected valid C.

createTemporarySymbol is what every other compiler temporary here already
uses. It also marks the slot an expression temp, so a discarded postfix
value now dies in dead code elimination: one fewer store per `x++;`
statement, and a smaller frame.
