John Ericson b9acfb4ecf treewide: isArm -> isAarch32
Following legacy packing conventions, `isArm` was defined just for
32-bit ARM instruction set. This is confusing to non packagers though,
because Aarch64 is an ARM instruction set.

The official ARM overview for ARMv8[1] is surprisingly not confusing,
given the overall state of affairs for ARM naming conventions, and
offers us a solution. It divides the nomenclature into three levels:

```
ISA:             ARMv8   {-A, -R, -M}
                 /    \
Mode:     Aarch32     Aarch64
             |         /   \
Encoding:   A64      A32   T32
```

At the top is the overall v8 instruction set archicture. Second are the
two modes, defined by bitwidth but differing in other semantics too, and
buttom are the encodings, (hopefully?) isomorphic if they encode the
same mode.

The 32 bit encodings are mostly backwards compatible with previous
non-Thumb and Thumb encodings, and if so we can pun the mode names to
instead mean "sets of compatable or isomorphic encodings", and then
voilà we have nice names for 32-bit and 64-bit arm instruction sets
which do not use the word ARM so as to not confused either laymen or
experienced ARM packages.

/** Packaging design:
- The basic mesa ($out) contains headers and libraries (GLU is in libGLU now).
This or the mesa attribute (which also contains GLU) are small (~ 2 MB, mostly headers)
and are designed to be the buildInput of other packages.
- DRI drivers are compiled into $drivers output, which is much bigger and
depends on LLVM. These should be searched at runtime in
"/run/opengl-driver{,-32}/lib/*" and so are kind-of impure (given by NixOS).
(I suppose on non-NixOS one would create the appropriate symlinks from there.)
- libOSMesa is in $osmesa (~4 MB)
