std: update std.builtin.Type fields to follow naming conventions
...
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938 .

elf: re-use old atom slot for a trampoline to that atom
...
This is the initial implementation of Jacob Young's idea of
re-using old function slots as trampolines for new function's
location. This way the trampoline is guaranteed to be aligned
to the function's alignment.
The only edge case is if an incremental update further overaligns
the function in which case we skip/delete the trampoline and
re-evaluate all references.
