Currently when multiple sections with different flags are implicitly
created in IR (for example, a read-only and writable values in the same
section) they are emitted in the same section with the flags of the
first one seen. Instead, add flags to the ELFUniqueIDMap so that unique
sections are emitted for each set of flags.
