Use revisions to test min_const_generics

[lcnr]

cc #74878

#74877 implemented feature(min_const_generics) which is split off from feature(const_generics).

As these two features have some meaningful differences it is desirable to run try and run all const generics tests with both features.

This can be done usingrevisions. Some tests were already updated in #74877:

rust/src/test/ui/const-generics/issues/issue-56445.rs

Lines 1 to 13 in f9c2177

	// Regression test for https://github.com/rust-lang/rust/issues/56445#issuecomment-518402995.
	// revisions: full min
	#![cfg_attr(full, feature(const_generics))] //[full]~WARN the feature `const_generics` is incomplete
	#![cfg_attr(min, feature(min_const_generics))]
	#![crate_type = "lib"]
	use std::marker::PhantomData;
	struct Bug<'a, const S: &'a str>(PhantomData<&'a ()>);
	//~^ ERROR: use of non-static lifetime `'a` in const generic
	//[min]~| ERROR: using `&'static str` as const
	impl Bug<'_, ""> {}

I'll work on part of it

[Amjad50]

Are all the tests done? Or is this being closed because of using the word "fixes" in #76514 ?

[lcnr]

because of the keyword "fixes". Don't think that all tests have been migrated yet

[hameerabbasi]

I migrated all of the relevant tests I could find. I could go back and look.

There are a few that simply didn't need revisions. Examples include things that test for the features being unstable and that const_generics and min_const_generics cannot be used together.

I changed "partially addresses" to "fixes" only when I believed I'd gotten through all of them.

[hameerabbasi]

I missed type_dependent and const_evaluatable_checked. I apologize for the confusion. PR incoming!
