x86_64: Fix up -fpic -mcmodel=large -fno-plt [PR98063]
On the following testcase with -fpic -mcmodel=large -fno-plt we emit
call puts@GOTPCREL(%rip)
but that is not really appropriate for CM_LARGE_PIC, the .text can be larger
than 2GB in that case and the .got slot further away from %rip than what can
fit into the signed 32-bit immediate.
The following patch computes the address of the .got slot the way it is
computed for that model for function pointer loads, and calls that.
