Luke Street e1ccee1e73 Improve data section diffing more
This re-implements the older algorithm
used for data and BSS section match
percentages. We perform both and
choose the highest match percent
between the two options.

Support R_MIPS_GPREL16 relocations correctly (#88)
* Support R_MIPS_GPREL16 relocations correctly

symbols defined in the same file require adding a
special ri_gp_value from the .reginfo section to
their relocation calculations.

* Run nightly rustfmt

* Prevent potential panic when slicing .reginfo
