This bound is already implicit through the AnyPrivate trait,
but since it is not explicit, you still have to write Box<Any + 'static>,
even though Any can only be 'static.
Introducing the 'static bound here makes this bound explicit, making
Box<Any> legal.
I don't know exactly what made this regress so badly…maybe it was all the lifetimes that @eddyb landed. According to `git blame` this is all somewhat old code. Regardless this is an enormous improvement in compile times.

This makes the windows `make dist` target start producing binary tarballs, and tweaks install.sh so they work, in preparation for working on a combined Rust+Cargo installer.
This is the bare minimum to stop using split stacks on Windows, fixing https://github.com/rust-lang/rust/issues/13259 and #14742, by turning on stack probes for all functions and disabling compiler and runtime support for split stacks on Windows.
It does not restore the out-of-stack error message, which requires more runtime work.
This includes a test that the Windows TCB is no longer being clobbered, but the out-of-stack test itself is pretty weak, only testing that the program exits abnormally, not that it isn't writing to bogus memory, so I haven't truly verified that this is providing the safety we claim.
A more complete solution is in https://github.com/rust-lang/rust/pull/16388, which has some unresolved issues yet.

Kind of a first draft because I'm not sure if this is the right approach. I believe the general idea of giving an error rather than an ICE in obligation_for_builtin_bound is right, but not sure about returning an Option, etc.
Also, could probably have a better error message.
The reason that 'ar' can fail with permission denied is that when
link-time optimizations are enabled, rustc copies libraries into a
temporary directory, preserving file permissions, and subsequently
modifies them using 'ar'.
The modification can fail because some package managers may install
libraries in system directories as read-only files, which means the
temporary file also becomes read-only when it is copied.
I have fixed this by giving the temporary file's owner read+write
permissions after the copy.
I have also added a regression test for this issue.
- Removes f128 from the grammar, which is no longer support in rustc
- The fragment modifier is added so it won't parse float suffix as a separate token
It's a rather useful syntax, and non-obvious.
A friend of mine is learning Rust and was trying to find a way to easily do such an initialization — he couldn't find it in the guide and was pretty surprised when I showed him. Looks like something that should be mentioned.
