Enums on hexagon use a smallest size (but at least 1 byte) that fits all
the enumeration values. This is unlike many other ABIs where enums are
at least 32 bits.

Fixes #82100

@nagisa
Could you add a

// needs-llvm-components: hexagon

annotation to the added test?
Otherwise it fails unless the hexagon backend for LLVM is built.
