Please test 1.0.0-beta2

[elliottslaughter]

We have a new beta towards our 1.0.0 release. This probably won't be the last, since there are still things we want to do. But anyway, progress!

See the release here: https://github.com/terralang/terra/releases/tag/release-1.0.0-beta2 (this includes binaries and a summary of changes since the last beta)

Like last time, let's try to make sure the release actually works everywhere we expect:

Test/OS	Linux	OSX	Windows
Test Suite w/o CUDA	✅ (Travis)	✅ (Travis)	✅ (AppVeyor)
Test Suite with CUDA
Rigel
Opt
Regent			N/A

Other todo items:

• Update documentation to include labels (was: New Terra release) #173 (document label([name]) and and for multiple functions)
• defer is not documented #154 (document defer)
• Please test 1.0.0-beta1 #323 (comment) (CUDA slowdown)
• Please document __for (and question about iterators) #333 (document __for)
• Problems testing terra[ Release 1.0.0-beta1 ] #366 (portability of Linux binaries)

Optional:

• Support Holy Build Box #388 (holy build box)

Would it be possible to get binaries compiled against LLVM 8+? LLVM 8 in particular brings the webassembly backend enabled by default, which is something that would be useful to have 'out of the box'.

Sure, is a Ubuntu 16.04 build ok? CUDA 9.2?

1.0.0-beta2 will run on Ubuntu >= 20.4, but requires "apt install libtinfo5"
