With clang 10 and up `getTemporary` has been replaced with the more versatile `getSubExpr`.

In the future we should re-write this checker but for now this solution is acceptable.

This is just drive-by, but it confused me. We require at least clang 4 to build
nowadays.

sccache-dist / icecream preprocess the file and then send it to a builder.
That means that the file contains #line directives or equivalents in order for
diagnostics and such to work correctly.
Unfortunately our clang-plugin build fails catastrophically if you include a
third-party header, as it doesn't account for them.
Use SourceManager::getPresumedLoc to get filenames, as it accounts for them,
unlike just getFilename.

In clang 9, the signature of `registerPPCallbacks` changed and it no longer provides us a `CompilerInstance` [0]. I couldn't find a way to reach the `CompilerInstance` from the new structures, so I've inserted a level into the class hierarchy that mimics the old functionality.
With this patch, clang-tidy compiles with either clang-8 or clang-9, so we can land this independently in preparation for bug 1573211.
[0] For reference: the new signature was introduced in bbc89dcb29, the old overload was marked deprecated in e9087fe75c and removed in ee737a84d7.

It doesn't really make sense to enforce this behavior for calls on stack
variables (which presumably we then want to do something with) and doesn't
necessarily make sense to enforce it for member variables either.

This patch is in support of adding a variant of Static{Auto,Ref}Ptr for use as
static locals, taking advantage of C++11 "magic statics" such that we can lazily
initialize those variables in a thread-safe way.
In support of those classes, this patch adds two new attributes:
* `moz_static_local_class` to ensure that any instantiations of that class only
occur as static local variables;
* `moz_trivial_dtor` to ensure that these classes do not implicitly call `atexit`
and add a whole bunch of shutdown crap.
`moz_static_local_class` works similarly to `moz_global_class`, except that its
object must only instantiate as static locals.
`TrivialDtorChecker` is based on `TrivialCtorDtorChecker`, with the ctor-specific
bits removed.

LLVM r356397 added some new warnings to the compiler that in this file complain about `size argument is too large; destination buffer has size 100, but size argument is 101`.
The easiest path is to just remove those lines; doing so doesn't really weaken the test coverage of the SprintfLiteral checker.

https://reviews.llvm.org/rL360311 reworked the handling of `explicit` in `CXXConversionDecl`, and the `isExplicitSpecified()` method no longer exists. We can instead use `isExplicit()` which conveniently works on both old and new clangs. (Before 360311, `isExplicit()` just forwarded to `isExplicitSpecified()`.)

Inheriting constructors are implicitly introduced via a using-declaration.
Since the C++ grammar doesn't allow attributes on using-declarations, it
is currently impossible to add MOZ_IMPLICIT to implicit inheriting
constructors.
This commit changes the AST matcher such that it ignores inheriting
constructors altogether. If they are inheriting from an implicit inherited
constructor, that constructor's check should be enough to ensure that no
constructors are unintentionally implicit.
