This is a temporary workaround for Fuchsia's libc not supporting
TLS segments with alignments greater than 32 bytes. It should
be reverted ASAP following the fix to libc.

Avoid unnecessary pattern matching against Option and Result

Move SmallVector and ThinVec out of libsyntax

- move `libsyntax::util::SmallVector` tests to `librustc_data_structures::small_vec`
- remove `libsyntax::util::SmallVector`
- move `libsyntax::util::thin_vec` to `librustc_data_structures::thin_vec`

Other than moving these data structures where they belong it allows modules using `SmallVector<T>` (`SmallVec<[T; 1]>`) to specify their own length (e.g. 8 or 32) independently from `libsyntax`.

[NLL] Use span of the closure args in free region errors

Also adds a note when one of the free regions is BrEnv.
In a future PR I'll change these messages to say "return requires", which should improve them a bit more.

Account for --remap-path-prefix in save-analysis

Fixes rust-lang#52549.

Didn't add a test since save-analysis is still unstable, only tested this locally. Should I add a test for that? If so, is run-make-fulldeps an appropriate format?

Session is already created with remapped working directory, so use that instead of the actual cwd.
This was the only place affected, since the rest of the paths in save-analysis are directly derived from files in spans from `sess.codemap()`, which already creates remapped ones.

The `-O -C no-prepopulate-passes` workaround doesn't seem to be needed anymore, so it works again for my version of GDB. Let's see what CI says.
