For mips64 switch statements in subroutines could generate

within the codegen EK_GPRel64BlockAddress. This was not
supported for direct object output and resulted in an assertion.
This change adds support for EK_GPRel64BlockAddress for

One fallout from this is to turn on rela relocations
for mips64 to match gas.

Ignore the documentation-suggested location for compile_commands.json

According to http://clang.llvm.org/docs/HowToSetupToolingForLLVM.html
it's suggested that compile_commands.json in the root of the LLVM source tree
should be a symlink to the json file produced by your build system of choice.
So here's a patch so it doesn't turn up in git status, etc.

Remove unnecessary cast that was also unnecessarily casting away constness.
...
Even looking at the revision history I couldn't quite piece together why this
cast was ever written in the first place, but I assume it was because of some
change in the inheritance, perhaps this function was reimplemented in a
derived type & this caller was meant to get the base version (& it wasn't
virtual)?

PVS-Studio noticed that EmitVBR64 would perform undefined behaviour if the

number of bits was bigger than 32. I checked every use of this function
that I could find and it looks like the maximum number of bits is 32, so I've
added an assertion checking this property, and a type cast to (hopefully) stop
PVS-Studio from warning about this in the future.
