mir: Gather move at SwitchInt, Assert terminators

Previously, `_1` was not marked as "definitely uninitialized" after a `switchInt(move _1)` terminator.

I think the same goes for the `assert` terminator.

Remove "static item recursion checking" in favor of relying on cycle checks in the query engine

Tests are changed to use the cycle check error message instead. Some duplicate tests are removed.

bbd64b2563 Slight modification to the as_ref example of std::option::Option 
A user in a reddit thread was confused by the name of the variable
"num_as_int"; they thought the example was trying to convert the
string "10" as if it were binary 2 by calling str::len(). In reality,
the example is simply demonstrating how to take an immutable reference
to the value of an Option. The confusion comes from the coincidence
that the length of the string "10" is also its binary representation,
and the implication from the variable names that a conversion was
occuring ("num_as_str" to "num_as_int").

This PR changes the example number to 12 instead of 10, and changes
the variable name from "num_as_int" to "num_length" to better
communicate what the example is doing.

70db41cdf7 Handle gdb command failure gracefully in compiletest 
Previously, if the gdb command was available, but threw an error, compiletest would panic.  This is obviously not good. Now, gdb is treated as missing if calling `gdb --version` does not output anything on stdout.

[docs] Minor wording changes to drain_filter docs

The docs currently say, "If the closure returns false, it will try again, and call the closure on the next element."  But this happens regardless of whether the closure returns true or false.

9f36a35e61 Rollup merge of #48221 - rkruppe:improve-ctypes-lint, r=estebank 
Overhaul improper_ctypes output

This snowballed into a rather big set of improvements to the diagnostics of the improper_ctypes lint. See commits for details, including effects of each change on the `compile-fail/improper-ctypes.rs` test (now a UI test), which is pretty gnarly and hopefully not representative of real code, but covers a lot of different error cases.

Fixes #42050

5fd8d18097 Rollup merge of #48157 - scottmcm:try-for-each, r=dtolnay 
Add Iterator::try_for_each

The fallible version of `for_each` aka the stateless version of `try_fold`.  Inspired by @cuviper's comment in https://github.com/rust-lang/rust/pull/45379#issuecomment-338370020 as a more direct and obvious solution than `.map(f).collect::<Result<(), _>>()`.

Like `for_each`, no need for an `r` version thanks to overrides in `Rev`.

detect wrong number of args when type-checking a closure

Instead of creating inference variables for those argument types, use
the trait error-reporting code to give a nicer error. This also
improves some other spans for existing tests.
