Fix typos in various generator files
Corrects typos across multiple source files in GCC's code generators.
This commit rectifies typos in several files within the code generator tools of GCC. These tools are responsible for creating source code from specifications, and these fixes improve the readability and maintainability.
In Details
This commit fixes typos across multiple files in gcc/ containing code generators. These generators produce C code from higher-level specifications (e.g. attribute tables, automata, GTY type system, matchers, etc). These files are typically maintained by a small group of experts.
For Context
Code generators are tools that automatically create source code based on predefined specifications. They save developers from manually writing repetitive code and ensure consistency. This commit fixes typos in the source code of GCC's code generator tools, improving their clarity and reducing the risk of errors.
