c5fa7776df Do not drop_in_place elements of Vec<T> if T doesn't need dropping 
With -O2, LLVM's inliner can remove this code, but this does not happen
with -O1 and lower. As a result, dropping Vec<u8> was linear with length,
resulting in abysmal performance for large buffers.

d7ec69a652 Rollup merge of #28526 - Manishearth:expand-clone, r=eddyb 
This reduces some clones of `Vec`s. These are not deep copies since the
token tree is made using `Rc`s, so this won't be a major improvement.

6db1a0ea7c Auto merge of #28497 - apasel422:issue-28493, r=Gankro 
When both the key and value types were zero-sized, `BTreeMap` previously
called `heap::allocate` with `size == 0` for leaf nodes, which is
undefined behavior, and jemalloc would attempt to read invalid memory,
crashing the process.

This avoids undefined behavior by allocating enough space to store one
edge in leaf nodes that would otherwise have `size == 0`. Although this
uses extra memory, maps with zero-sized key types that have sensible
implementations of the ordering traits can only contain a single
key-value pair (and therefore only a single leaf node), and maps with
key and value types that are both zero-sized have few uses, if any.

Furthermore, this is a temporary fix that will likely be unnecessary
once the `BTreeMap` implementation is rewritten to use parent pointers.

Closes #28493.

d557f4a60f Rollup merge of #28485 - Wallacoloo:clarify-let-lhs, r=alexcrichton 
In code like `let x = 5`, I am initially confused as to the meaning of "let doesn't take a name on the left hand side, it actually accepts a pattern." - I interpret that as the pattern being located as: `<pattern> let [...]`.

I think what is meant is that the name/pattern is on the left hand side *of the assignment*, rather than to the left of the *let* statement. This change clarifies that.

6872d13e96 Rollup merge of #28400 - badboy:disable-browser-history-on-file, r=steveklabnik 
history.pushState is defined, but not working whenever document.origin is "null"
(literally that string, not just the null object).
This is due to some security considerations and is unlikely to be ever working.

For now just disable the usage of the history API when the documentation
is accessed through a file:/// URL.

See https://code.google.com/p/chromium/issues/detail?id=301210 for a
Chrome-specific issue on the history API on file:/// URLs

655b2ef45f Auto merge of #28495 - semarie:stdcpp-name, r=alexcrichton 
it makes rustc compatible with gcc installation that are using
`--program-transform-name' configure flag (on OpenBSD for example).

- detects at configure the name of stdc++ library on the system

- use the detected name in llvm makefile (with enable-static-stdcpp),
  and pass it to mklldeps.py

- generate mklldeps.rs using this detected name

note that CFG_STDCPP_NAME is about stdc++ name, not about libc++. If
using libc++, the default name will be `stdc++', but it won't be used
when linking.

r? @alexcrichton 

I added this support globally instead of just for OpenBSD as it isn't specially related to OpenBSD (except OpenBSD use it for gcc-4.9). And as I would had to change `llvm.mk', having just a default value in `configure' for others platforms won't be very useful.
