Fix typos in various Fortran files
Corrects typos found in multiple Fortran-related source files.
This commit resolves typos in various files within the Fortran front end of GCC, which improves the code’s readability and maintainability. The typos are spread across different parts of the Fortran compiler, including code checking, class handling, dependency analysis, expression handling, and code generation.
In Details
Fixes typos across multiple files in gcc/fortran/. These files implement the Fortran language front-end for GCC, including parsing, semantic analysis, code generation, and OpenMP support. Most toolchain developers outside the Fortran team wouldn't be familiar with these files.
For Context
This commit addresses typos in the Fortran language support within the GCC compiler. The Fortran front end translates Fortran code into a form that GCC can process. Correcting these typos makes the Fortran compiler's source code easier to understand and maintain, reducing the risk of errors.
