698b956a9f Auto merge of #50391 - nnethercote:escape_unicode, r=eddyb 
Use escape_default() for strings in LitKind::token().

This avoids converting every char to \u{...} form, which bloats the
resulting strings unnecessarily. It also provides consistency with the
existing escape_default() calls in LitKind::token() used for raw
string literals, char literals, and raw byte char literals.

There are two benefits from this change.

- Compilation is faster. Most of the rustc-perf benchmarks see a
  non-trivial speedup, particularly for incremental rebuilds, with the
  best speedup over 13%, and multiple others over 10%.

- Generated rlibs are smaller. An extreme example is libfutures.rlib,
  which shrinks from 2073306 bytes to 1765927 bytes, a 15% reduction.

427c548749 Auto merge of #50378 - varkor:repr-align-max-29, r=eddyb 
Reduce maximum repr(align(N)) to 2^29

The current maximum `repr(align(N))` alignment is larger than the maximum alignment accepted by LLVM, which can cause issues for huge values of `N`, as seen in #49492. Fixes #49492.

9e3cbbb60a Auto merge of #50369 - pftbest:unicode, r=SimonSapin 
Fix a warning in libcore on 16bit targets.

This code is assuming that usize >= 32bits, but it is not the case on
16bit targets. It is producing a warning that can fail the compilation
on MSP430 if deny(warnings) is enabled.
It is very unlikely that someone would actually use this code on
a microcontroller, but since unicode was merged into libcore we
have to compile it on 16bit targets.

I've tried to make sure that the code stays the same on x86,
here is an assembly comparison: https://godbolt.org/g/wFw7dZ

Fix an unresolved import issue with enabled `use_extern_macros`

This is a kinda ugly special-purpose solution that will break if we suddenly add a fourth namespace, but I hope to come up with something more general if I get to import resolution refactoring this summer.

360cbf2f48 change skolemizations to use universe index 
This is sort of confusing "side step". All it does is to change the
representation of a skolemized region. but the source of that universe
index is not the inference context, which is what we eventually want,
but rather an internal counter in the region inference context.

We'll patch that up later. But doing this now ought to help with
confusing diffs later.

This gives each type inference variable a notion of universe but doesn't

never interact with siblings.
