[SPARC][MC] Fix `%gdop_hix22()` and `%gdop_lox10()` to use correct relocations (#137915)
1bfc5e7 introduced support for `%gdop_hix22()` and `%gdop_lox10()`.
However, it incorrectly mapped them to `R_SPARC_GOTDATA_HIX22` and
`R_SPARC_GOTDATA_LOX10`. They should in fact emit
`R_SPARC_GOTDATA_OP_HIX22` and `R_SPARC_GOTDATA_OP_LOX10`.
This became a problem when assembling glibc's PIC startup code:
```asm
sethi %gdop_hix22(main), %o0
xor %o0, %gdop_lox10(main), %o0
ldx [%l7 + %o0], %o0, %gdop(main)
```
After the `xor`, `%o0` should contain the GOT offset for `main`, but
because of the incorrect relocations, it actually ends up containing the
address of `main`, which of course makes the following `ldx` fail.
