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.

The old code for member method calls did the following:
1) Find the member method calls.
2) Look at their "this" expression.
3) If the "this" is an operator call, check for any of the arguments of the
operator call being invalid.
4) Otherwise (if not an operator call) check for the "this" value being
invalid.
This wasn't right, because the "is invalid" check checks the type and only
considers refcounted things. So if the code looked something like
"foo[i]->call_method()", we would look at the types of "foo" and "i" and
determine that none of those are refcounted types so there is nothing invalid
here (since "foo" is some sort of array type and "i" is an integer). The new
setup just checks whether the "this" value is invalid, which does the type
check on the "this" value itself; in the "foo[i]->call_method()" case on
"foo[i]". We then adjust the exclusions in InvalidArg to consider operator->
on known-live things valid, to allow the thing that we were really trying to
accomplish with the "check for an operator call" bits:
"stackRefPtr->some_method()".
The test coverage being added for the made-up TArray type is meant to catch
things like the geolocation issue that was being hidden by the buggy behavior.
I'm not using nsTArray itself because some header included by nsTArray.h
tries to define operator new/delete bits inline and that triggers warnings that
then cause a clang-plugin test failure, because they're unexpected.

This allows calling a C++ MOZ_CAN_RUN_SCRIPT method that takes a callback argument.
The changes to TestCanRunScript.cpp are there to catch an incorrect change I was
going to make to the analysis to make this work, until I figured out that
RootedCallback should be MOZ_IS_SMARTPTR_TO_REFCOUNTED.

can detect that it's possibly calling a MOZ_CAN_RUN_SCRIPT thing without having

In the first part of bug 1501903, paths were canonicalized in
inThirdPartyPath. For some reason, this seems to add a non-negligible
overhead on Windows. OTOH, most include paths handed by the build system
are absolute, and most paths that contains .. are for system headers,
which don't matter for the inThirdPartyPath test.
Considering the inThirdPartyPath has been using non-canonicalized paths
for the longest, we'll assume it's fine to come back to that mode.

This is necessary because:
(a) the JSONFormatter emits a \n newline for each analysis line
(b) we truncate the file to the expected length after writing it
(c) on Windows writing the file in text mode replaces \n with \r\n
and invalidates our computed "expected length"

SourceLocation that are passed to inThirdPartyPath might be macro
expansion locations, for which SourceManager.getFilename returns the
path of the directory containing the source, rather than of the
expansion location.
Furthermore, the paths getFileName returns are not canonical, and can
contain e.g. `..`.
