Subject: [PATCH] [Flang][Lower] NFC: Update target-features/target-cpu tests

Previously, some of these lowering tests inadvertently relied on a default
triple not introducing any target features. This caused failures when compiling
on a ppc64le-linux-unknown-gnu system.

This patch updates these lowering tests to always explicitly set the target
triple and check that the -target-cpu and -target-features compiler options are
processed as expected.
