Pete Vine:

On ARM Linux, running [this](https://github.com/rust-lang/rust/blob/master/src/etc/platform-intrinsics/generator.py) script and [this](https://github.com/rust-lang/rust/blob/master/src/etc/platform-intrinsics/aarch64.json) data file we get the following results:

`time python generator.py --format compiler-defs aarch64.json -o out`

real    0m0.639s
user    0m0.600s
sys     0m0.030s

`time pypy generator.py --format compiler-defs aarch64.json -o out`

real    0m1.886s
user    0m1.720s
sys     0m0.150s

using python 2.7.6 and pypy 5.0.0 respectively.
