  [SystemZ][z/OS] Fix "relative immediate relocation section mismatch" (#222437)

Constants should go inside the text section, but this is not explicitly
coded. In the test case, the EH table is generated into a PR section.
Then the constant pool of function `fn_with_const_pool()` is emitted,
which goes into the PR section of the EH table instead of the code
section. When the constant is later referenced in the code, the relative
offset cannot be calculated because different sections are involved.
The fix is to explicitly return the text section for constants.
