Ada: Remove unnecessary Is_Boolean_Aspect flag.
The Ada compiler removes the Is_Boolean_Aspect flag, which was unnecessary and had an incorrect comment.
The Ada compiler removes the Is_Boolean_Aspect flag from gen_il-fields.ads, gen_il-gen-gen_nodes.adb, sinfo.ads, and sem_ch13.adb. This flag was deemed unnecessary, and its associated comment was incorrect. The change also includes minor comment improvements in other files.
In Details
The commit removes the Is_Boolean_Aspect flag from the gen_il components of the Ada front end, specifically within gen_il-fields.ads, gen_il-gen-gen_nodes.adb, sinfo.ads, and sem_ch13.adb. This flag likely related to how boolean aspects were represented in the intermediate language. Removing the flag simplifies the code and removes a source of potential confusion.
For Context
The Ada front end for GCC transforms Ada source code into an intermediate representation suitable for further processing by the compiler. This commit cleans up internal flags no longer needed. Such flags often represent temporary solutions or experimental features that, over time, become obsolete as the compiler evolves and its internal architecture is refined. Removing them reduces complexity and makes the compiler easier to maintain.
