Find all the usages of `--enable-experimental-feature` or `--enable-upcoming-feature` in the tests and replace some of the `REQUIRES: asserts` to use `REQUIRES: swift-feature-Foo` instead, which should correctly apply to depending on the asserts/noasserts mode of the toolchain for each feature. Remove some comments that talked about enabling asserts since they don't apply anymore (but I might had miss some). All this was done with an automated script, so some formatting weirdness might happen, but I hope I fixed most of those. There might be some tests that were `REQUIRES: asserts` that might run in `noasserts` toolchains now. This will normally be because their feature went from experimental to upcoming/base and the tests were not updated.

// Regression test for a runtime failure that used to happen under some very specific conditions: (1) LTO, (2) Swift
|
|
// compiler is used with -num-threads to emit multiple .o files even in WMO mode, (3) the first listed source file
|
|
// contains no code that would trigger the use of swift_initStaticObject runtime function (e.g. no array literals), (4)
|
|
// another source file does use swift_initStaticObject that doesn't get optimized away (e.g. an array literal in a
|
|
// never-inline function, but not an empty array). In that case, we used to have a mismatching calling convention on
|
|
// swift_initStaticObject that the LTO pipeline would conclude is invalid IR and replace it with an unconditional trap.
