Alex Bradbury ca81a56f65 [RISCV] Don't evaluatePCRelLo if a relocation will be forced (e.g. due to linker relaxation)
A pcrel_lo will point to the associated pcrel_hi fixup which in turn points to
the real target. RISCVMCExpr::evaluatePCRelLo will work around this
indirection in order to allow the fixup to be evaluate properly. However, if
relocations are forced (e.g. due to linker relaxation is enabled) then its
evaluation is undesired and will result in a relocation with the wrong target.

This patch modifies evaluatePCRelLo so it will not try to evaluate if the
fixup will be forced as a relocation. A new helper method is added to
RISCVAsmBackend to query this.
