  [SystemZ] Fix a bug introduced by #135767 (#138280)

Commit `083b4a3d66` introduced a store-and-load pair around the `BRASL`
call to mcount. That load instruction did not properly declare its
target register as defined, leading to a bad machine instruction.

This commit fixes this by explicitly labeling `%r14` on the load as
`def`.
