The ISO 8601 standard does not mandate any specific precision for
fractional seconds, so this accepts input of any length, ignoring the
part after the nanoseconds place. It may be more correct to round with
the tenths of nanoseconds digit, but then we'd have to deal with
carrying the round through the entire Tm struct (e.g. for a time like
Dec 31 11:59.999999999999).
%f is the format specifier that Python's datetime library uses for
0-padded microseconds so it seemed appropriate here.

Parts I'm unsure about and would like a reviewer to look at are:
* `pub trait GenericPath : Clone + Eq + ToStr` -- is this the done thing? I've never done trait inheritance before, let alone from multiple traits, but it seemed to be necessary to be able to call all the methods we have to be able to call on `self`.
* changing the argument of `components` from `self` to `&self`, and having it return `self.components.clone()` instead of `self.components`; this was necessary to avoid move errors, but I'm not sure if it's the right thing. (The default methods impls now all have to call `self.components()` instead of just referencing the field `self.components`.)
Rationale: having a function which fails means that the location of
failure which is output is that of the unreachable() function, rather
than the caller.
This is part of #8991 but is not all of it; current usage of
``std::util::unreachable()`` must remain so for the moment, until a new
snapshot is made; then I will remove that function entirely in favour of
using this macro.
Also redefine all of the standard logging macros to use more rust code instead
of custom LLVM translation code. This makes them a bit easier to understand, but
also more flexibile for future types of logging.
Additionally, this commit removes the LogType language item in preparation for
changing how logging is performed.
These commits fix bugs related to identically named statics in functions of implementations in various situations. The commit messages have most of the information about what bugs are being fixed and why.
As a bonus, while I was messing around with name mangling, I improved the backtraces we'll get in gdb by removing `__extensions__` for the trait/type being implemented and by adding the method name as well. Yay!

Remove __extensions__ from method symbols as well as the meth_XXX. The XXX is
now used to append a few characters at the end of the name of the symbol.

This is currently unsound since `bool` is represented as `i8`. It will
become sound when `bool` is stored as `i8` but always used as `i1`.
However, the current behaviour will always be identical to `x & 1 != 0`,
so there's no need for it. It's also surprising, since `x != 0` is the
expected behaviour.

Reject codepoints \uD800 to \uDFFF which are the surrogates
(reserved/unused codepoints that are invalid to encode into UTF-8)
The surrogates is the only hole of invalid codepoints in the range from
\u0 to \u10FFFF.

A [dialogue](https://github.com/mozilla/rust/pull/8909#discussion-diff-6102725) on PR #8909 inspired me to make this change.
r? anyone
(It is possible that `std::path` itself will soon be replaced with a new implementation that kballard's working on, as mentioned in the dialogue linked above, but this revision is simple enough that I figured I'd offer it up.)
gather_loans does not need to recurse into any items declared in the
current block. Rather than special-case `fk_item_fn` and `fk_method`,
just make the GatherLoanVisitor's visit_item method a no-op.
This indirectly implies that the example of #7740 is fixed:
fn f() {
static A: &'static char = &'A';
}
Since we do not recurse into items, we no longer encounter `&'A'`.
