I struggled a bit with drawing the line about where the basic tunes were and where
the rest of them go.

The previous structure was like so.

include/mips/arch-mips.inc had the following tunes : "mips mips64-n32 mips64 mipsel
mips64el-n32 mips64el mips-nf mips64-nf-n32 mips64-nf mipsel-nf mips64el-nf-n32 mips64el-nf"

Which is a mix of 32/64 bit.

Then
include/tune-mips32.inc defined "mips32 mips32el mips32-nf mips32el-nf"
include/tune-mips32r2.inc defined "mips32r2 mips32r2el mips32r2-nf mips32r2el-nf"

include/tune-mips64.inc just had a require include/tune-mips32r2.inc which
includes the base which basically has the actual mips64 tunes.

With this restructure patch.

include/mips/arch-mips.inc defines no tunes.
include/tune-mips32.inc defines mips and mips32
include/tune-mips32r2.inc defines mips32r2
include/tune-mips64.inc defines mips64
include/tune-mips64r2.inc defines mips64r2

I could leave the existing layout as is and only add 64r2 as a separate patch.
But as I was poking around here, I tried to improve things a bit.

Any recommendation regarding which way would be preferred?

Thanks for pointing this out. I'll fix this in v3.
