C parser: Remove errant `optimize` pragma
An unintended `#pragma optimize` was removed from the GCC C parser.
An accidental #pragma optimize directive and a whitespace change in a comment were removed from the C parser. These changes were introduced in a previous commit but were not intended to be part of the final code.
In Details
The C parser in GCC (c-parser.cc) handles syntactic analysis of C code. Accidental inclusion of debugging pragmas can sometimes occur during development. This commit removes an unintended #pragma optimize from the parser.
For Context
The C parser is the part of the compiler that reads your code and turns it into an internal representation the rest of the compiler can understand. Pragmas are special directives that can control the behavior of the compiler, often for debugging purposes. This commit removes a stray pragma that should not have been present in the production code.
