As per issue rust-lang#54985 removes the not useful suggestion to remove asterisk in
move errors. Includes minor changes to tests in the `ui` suite to account
for the removed suggestion.

This fixes an ICE when building libcore with `-Z mir-opt-level=3`.

This shaves of 50 minutes of cycle time on Azure and will likely also
save a significant chunk of time on Travis. The assertions here aren't
really buying us much over other builders with assertions already
enabled, so let's disable them for this builder.

cc rust-lang#61185

This is by no means exhaustive, but I noticed a few grammatical errors
when reading the documentation, and decided just to push these.

Some standard rules/guidelines I followed:

 * Do not split infinitives, ie "not to move" instead of "to not move"

 * Do not use "since" when you want to say "because" or "as" - the word
   "since" has a temporal meaning

In addition:

 * Fix a small typo: "Similarily" should be "Similarly"

 * Delete double-spaces after full stop

This also makes sure people don't contruct these the wrong way

Remove asterisk suggestion for move errors in borrowck

As per the decision in rust-lang#54985 completely removes the suggestion to add an asterisk when checking move errors. I believe I've preserved the correct behavior with the "consider borrowing here" branch of the original match arm, but I'm not positive on that.

This is my first PR to rustc so any feedback is greatly appreciated. Thanks.

Increases heap size available during testing for SGX

PR [61540](rust-lang#61540) causes at least one test to fail when run for the SGX platform due to lack of memory. This PR increases the heapsize available during tests, which is a good thing regardless of the status of that PR.

This also makes sure people don't contruct these the wrong way (i.e., not through the `From` instance).
