Alex Crichton ef90d32f07 rustc: Always emit the uwtable attribute on Windows ...

This commit alters the translation layer to unconditionally emit the `uwtable`
LLVM attribute on Windows regardless of the `no_landing_pads` setting.
Previously I believe we omitted this attribute as an optimization when the
`-Cpanic=abort` flag was passed, but this unfortunately caused problems for
Gecko.

It [was discovered] that there was trouble unwinding through Rust functions due
to foreign exceptions such as illegal instructions or otherwise in-practice
methods used to abort a process. In testing it looked like the major difference
between a working binary and a non-working binary is indeed this `uwtable`
attribute, but this PR has unfortunately not been thoroughly tested in terms of
compiling Gecko with `-C panic=abort` *and* this PR to see whether it works, so
this is still somewhat working on just suspicion.
