To ensure the proper functioning of the jump_label test module, this patch
adds support for the R_OR1K_32_PCREL relocation type for any modules. The
implementation calculates the PC-relative offset by subtracting the
instruction location from the target value and stores the result at the
specified location.

When testing modules in OpenRISC I found R_OR1K_AHI16 (signed adjusted
high 16-bit) and R_OR1K_SLO16 (split low 16-bit) relocations are used in
modules but not implemented yet.
This patch implements the relocations. I have tested with a few modules.

This defines the current OpenRISC relocation types using the current
R_OR1K_* naming conventions.
The old R_OR32_* definitions are left for backwards compatibility.
Note, the R_OR32_VTENTRY and R_OR32_VTINHERIT macros were defined with
the wrong values the have always been 7 and 8 respectively, not 8 and 7.
They are not used for module loading and I have updated them to use the
correct values.

Move the pointer increments to the dereference statements to avoid
incompatible pointer assignments, and remove superfluous casts.
