Add intrinsic to create an integer bitmask from a vector mask
This PR adds a new simd intrinsic: `simd_bitmask(vector) -> unsigned integer` that creates an integer bitmask from a vector mask by extracting one bit of each vector lane.
This is required to implement: https://github.com/rust-lang-nursery/packed_simd/issues/166 .
EDIT: the reason we need an intrinsics for this is that we have to truncate the vector lanes to an `<i1 x N>` vector, and then bitcast that to an `iN` integer (while making sure that we only materialize `i8`, ... , `i64` - that is, no `i1`, `i2`, `i4`, types), and we can't do any of that in a Rust library.

Ignore line ending on older git versions
On Ubuntu 16.04 git 2.7.4 tries to fix the line ending of `.png` and `.ico` files, and obviously it ruins them. This PR adds an attribute to those files to ignore which line ending they use.

Fix issue 57762
against a stock LLVM 7. LLVM 7 was released without a necessary fix
for a bug in the DWARF discriminant code.
This patch changes rustc to use the fallback mode on (non-Rust) LLVM 7.
Closes#57762
Add error for trailing angle brackets.
Fixes#54521.
This PR adds a error (and accompanying machine applicable
suggestion) for trailing angle brackets on function calls with a
turbofish.

This paragraph was written for Rust 2015. Since 2018 has been stable for a while I think we can update it.
Fix Android CI failing to download SDKs
A component of the Android SDK now requires an additional license ([full license text](https://gist.github.com/pietroalbini/28b46a6fed0921d129de58e7aef29f11)) to be accepted before it's possible to use it. The license is dated January 16th 2019, so it's recent.
The weird thing about the license is that it doesn't prompt you to accept it during `sdkmanager --licenses` like all the other ones, but during `sdkmanager platform-tools emulator ...`, and we didn't pipe `yes` to it before this PR.
The PR changes the SDK installation script to accept all the licenses even on the `sdkmanager platform-tools emulator` command.
On Ubuntu 16.04 git 2.7.4 tries to fix the line ending of .png and .ico

those files to properly mark them as binary.

[rust-gdb] relax the GDB version regex
The pretty-printer script is checking `gdb.VERSION` to see if it's at
least 8.1 for some features. With `re.match`, it will only find the
version at the beginning of that string, but in Fedora the string is
something like "Fedora 8.2-5.fc29". Using `re.search` instead will find
the first location that matches anywhere, so it will find my 8.2.
In particular, the table entries (associated with type-variables
created during the probe) must persist as long as the candidates
assembled during the probe. If you make a nested probe without
creating a nested `ProbeContext`, the table entries are popped at the
end of the nested probe, while the type-variables would leak out via
the assembled candidates attached to `self` (the outer
`ProbeContext`). This causes an ICE (*if you are lucky*)!
const_eval: Predetermine the layout of all locals when pushing a stack frame
Usually the layout of any locals is required at least three times, once
when it becomes live, once when it is written to, and once it is read
from. By adding a cache for them, we can reduce the number of layout
queries speeding up code that is heavy on const_eval.
Fix memory leak in P::filter_map
Probably this function isn't widely used, but anyway this wasn't working as intended.

Remove unnecessary dummy span checks
The emitter already verifies wether a given span note or span label
can be emitted to the output. If it can't, because it is a dummy
span, it will be either elided for labels or emitted as an unspanned
note/help when applicable.
