55e5618eab [test] Match nocapture to succeed both on main and rebranch
Both the syntax and relative order of the LLVM `nocapture` parameter
attribute changed upstream in 29441e4f5fa5f5c7709f7cf180815ba97f611297.
To reduce conflicts with rebranch, adjust FileCheck patterns to expect
both syntaxes and orders anywhere the presence of the attribute is not
critical to the test. These changes are temporary and will be cleaned
up once rebranch is merged into main.

17fc00f8a7 [test] IRGen: Adjust FileCheck patterns for new nuw attribute in upstream LLVM
This attribute was introduced in
7eca38ce76d5d1915f4ab7e665964062c0b37697 (llvm-project).

Match it using a wildcard regex, since it is not relevant to these
tests.

This is intended to reduce future conflicts with rebranch.

4858cb6225 [IRGen][interop] do not add 'nocapture' to not bitwise takable types
The use of 'nocapture' for parameters and return values is incorrect for C++ types, as they can actually capture a pointer into its own value (e.g. std::string in libstdc++)

0ae9e68607 [metadata prespecialization] On by default.
Previously, -Xfrontend -prespecialize-generic-metadata had to be passed
in order for generic metadata to be prespecialized.  Now it is
prespecialized unless -Xfrontend
-disable-generic-metadata-prespecialization is passed.
