This sounds like a symptom of not running from the MinGW shell (an 
unfortunate limitation in our Windows build). There are some 
instructions for getting MinGW setup on the wiki.

So it won't work with MinGW64 either will it?

No, we only support 32-bit windows targets at the moment. This is not a long-term limitation, just a matter of ports we've done vs. not-yet-done; 64bit works on linux and osx presently.

Also this is pretty much just a dupe of #2871 (we've had lots of people hit it). It's not going to be solved this release, sadly. Closing as duplicate.

All you have to do is copy that particular .dll from the bin folder of MinGW. I'm on windows 64 bit and it works just fine.

Don't panic on license check errors (rust-lang#3655)
e0e2f0d 
Without this case, an ErrorKind::LicenseCheck results in a panic:

    thread 'main' panicked at 'internal error: entered unreachable code', src/tools/rustfmt/src/formatting.rs:320:18

N.B.: errors of this type are only raised when the configuration file
contains `license_tempate_path = "TEMPLATE_FILE"`.

portable-simd: add test for non-power-of-2 bitmask

`@calebzulawski` is that the intended behavior? Specifically for arrays, the bitmask `[1, 0, 0, 1, 0, 0, 1, 0, 1, 0]` becomes
- `[0b01001001, 0b01]` on little endian
- `[0b10010010, 0b10]` on big endian
