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

7f3444e1ba Auto merge of #49513 - nox:univariant-fieldless-enum-as-zst, r=eddyb 
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.
