c8c3579bff Fix closure arguments which are immediate because of field reordering. 
While building immediates goes through type_of::type_of, extracting them must account for field reorderings.

ebec55406b Auto merge of #37824 - jseyfried:symbols, r=eddyb 
Clean up `ast::Attribute`, `ast::CrateConfig`, and string interning

This PR
 - removes `ast::Attribute_` (changing `Attribute` from `Spanned<Attribute_>` to a struct),
 - moves a `MetaItem`'s name from the `MetaItemKind` variants to a field of `MetaItem`,
 - avoids needlessly wrapping `ast::MetaItem` with `P`,
 - moves string interning into `syntax::symbol` (`ast::Name` is a reexport of `symbol::Symbol` for now),
 - replaces `InternedString` with `Symbol` in the AST, HIR, and various other places, and
 - refactors `ast::CrateConfig` from a `Vec` to a `HashSet`.

84415ea1f2 [LLVM 4.0] Set EH personality when resuming stack unwinding 
To resume stack unwinding, the LLVM `resume` instruction must be used.

In order to use this instruction, the calling function must have an
exception handling personality set.

LLVM 4.0 adds a new IR validation check to ensure a personality is
always set in these cases.

This was introduced in [r277360](https://reviews.llvm.org/rL277360).

36340ba994 rustc: move mir::repr::* to mir. 2016-10-28 10:37:24 +03:00

ee338c31fe normalize types every time HR regions are erased 
Associated type normalization is inhibited by higher-ranked regions.
Therefore, every time we erase them, we must re-normalize.

I was meaning to introduce this change some time ago, but we used
to erase regions in generic context, which broke this terribly (because
you can't always normalize in a generic context). That seems to be gone
now.

Ensure this by having a `erase_late_bound_regions_and_normalize`
function.

Fixes #37109 (the missing call was in mir::block).

b49a26ec6f invoke drop glue with a ptr to (data, meta) 
This is done by creating a little space on the stack. Hokey, but it's
the simplest fix I can see.

798be90648 introduce an unreachable terminator 
Use it instead of a `panic` for inexhaustive matches and correct the
comment. I think we trust our match-generation algorithm enough to
generate these blocks, and not generating an `unreachable` means that
LLVM won't optimize `match void() {}` to an `unreachable`.

bb4b3fb7f9 Auto merge of #32202 - arielb1:slice-patterns, r=nikomatsakis 
Implement RFC495 semantics for slice patterns

non-MIR translation is still not supported for these and will happily ICE.

This is a [breaking-change] for many uses of slice_patterns.
