Rafael Espindola 4b6833332b Rewrite our relocation processing. 
This splits relocation processing in two steps.

First, analyze what needs to be done at the relocation spot. This can
be a constant (non preemptible symbol, relative got reference, etc) or
require a dynamic relocation. At this step we also consider creating
copy relocations.

Once that is done we decide if we need a got or a plt entry.

The code is simpler IMHO. For example:

- There is a single call to isPicRel since the logic is not split
  among adjustExpr and the caller.
- R_MIPS_GOTREL is simple to handle now.
- The tracking of what is preemptible or not is much simpler now.

This also fixes a regression with symbols being both in a got and copy
relocated. They had regressed in r268668 and r268149.

The other test changes are because of error messages changes or the
order of two relocations in the output.
