Rationale for this change
On riscv64, Gandiva fails at runtime with:
JIT session error: relocation target ... is out of range of R_RISCV_HI20 fixup ...What changes are included in this PR?
I set the PIC relocation model on the JIT TargetMachine for RISC-V manually to restore pre #49063 behavior. LLJIT normally sets Reloc::PIC_ for JITLink targets in prepareForConstruction, but #49063 builds the object-cache TargetMachine before that runs, so it gets the target-default (Static) model.
Are these changes tested?
Yes, by the existing Gandiva tests, on riscv64 hardware.
Are there any user-facing changes?
No public API changes. Gandiva expression evaluation now works on riscv64.
