8db1ad6222 Cherry-pick [Swiftify] Don't import counted_by with suffixed integer literals (#82469) (#82594)
Integer literal expressions with types that are not of type `int` are
printed with a suffix to indicate the type (e.g. `123U` or `456L` for
`unsigned` and `long`). This is not valid syntax for integer literals in
Swift, so until we fully translate the count expr syntax to Swift we
need to avoid importing these count expressions.

Also fixes some -Werror related stuff in test cases.

8be78da6de [Swiftify] Do not swiftify non-Swift-like counted_by exprs
__counted_by (and __sized_by) expressions can have arbitrary C syntax
in them, such as:

    void foo(int * __counted_by(*len) p, int *len);

When @_SwififyImport tries to generate Swift code for this, the
expression `*len` leads to a syntax error, since it isn't valid Swift.

This patch adds a check to ensure we only attach the Swiftify macro to
__counted_by expressions that are also syntactically valid in Swift.
