[DebugInfo] DISubprogram flags get their own flags word. NFC.

This will hold flags specific to subprograms. In the future
we could potentially free up scarce bits in DIFlags by moving
subprogram-specific flags from there to the new flags word.

This patch does not change IR/bitcode formats, that will be
done in a follow-up.
