bc16b8e92a Port existing callers of evaluate_obligation to the new canonical trait query 
Except the one in coherence, which needs support for intercrate mode.

79f71f976a Refactor overflow handling in traits::select to propagate overflow instead of aborting eagerly 
We store the obligation that caused the overflow as part of the OverflowError, and report it at the public API endpoints (rather than in the implementation internals).

20ad427af0 rustc: Emit uwtable for allocator shims 
This commit emits the `uwtable` attribute to LLVM for platforms that require it
for the allocator shims that we generate to ensure that they can hopefully get
unwound past. This is a stab in the dark at helping
https://bugzilla.mozilla.org/show_bug.cgi?id=1456150 along.

7d8f0e22f5 Auto merge of #50253 - nikomatsakis:regressions-2018-04-26, r=eddyb 
drop elaboration should reveal all

This used to happen implicitly through the normalization function; but we now keep the param-env as is, which seems less surprising.

cc #49685

Treat repr(Rust) univariant fieldless enums as ZSTs

This makes all those enums be represented the same way:

```rust
enum A1 { B1 }
enum A2 { B2 = 0 }
enum A3 { B3, C3(!) }
```

Related to #15747.

a2a9cc68fe rustc: Disable threads in LLD for wasm 
Upstream bug reports (rustwasm/wasm-bindgen#119) show that this may be the
culprit of odd crashes/hangs. The linker is a tiny fraction of build time anyway
right now so let's disable it and figure out how to possibly reenable it later
if necessary.

2e4f66a86f Make dump_{alloc,allocs,local}() no-ops when tracing is disabled. 
Because they traverse data structures and build up strings, which is
wasted effort if those strings aren't printed.

The patch also removes some now-unnecessary log_enabled! tests at call
sites.
