669191bca9 Auto merge of #1331 - samrat:macos-mach-timebase-info, r=RalfJung
Implement `mach_timebase_info` for macOS

Since we return nanoseceonds instead of ticks from `mach_absolute_time`, we don't need to scale the absolute time

Fixes #1288

organize intrinsics in groups

Also remove `pref_align_of` as it was moved into rustc long ago, and `align_of_val` as it doesn't exist (the name is `min_align_of_val`, which we also already handle).

Even more float cast tests

Copy a bunch of float cast tests from https://github.com/WebAssembly/testsuite/blob/master/conversions.wast. I didn't do all of them though, too lazy... maybe we should have a wasm interpreter written in Rust and run that in Miri and use the wasm test suite directly that way? :P

compile-fail test organization

Move compile-fail tests to appropriate directories.

(run-pass tests often test many things in one file, organized by functions. But for compile-fail tests that is not possible.)

2e82a8dc9e Auto merge of #1304 - RalfJung:backtrace-sep, r=RalfJung
add empty line before backtrace, to separate it from help text

I think this improves how things look, and makes it easier to see the help text (it currently kind of drowns next to the backtrace).
