& operator (ignoring any overloaded operator& for the type). The purpose of
this builtin is for use in std::addressof, to allow it to be made constexpr;
the existing implementation technique (reinterpret_cast to some reference type,
take address, reinterpert_cast back) does not permit this because
reinterpret_cast between reference types is not permitted in a constant
expression in C++11 onwards.

Previously, we asserted that whenever 'new' did not include a constructor
call, the type must be a non-record type. In C++11, however, uniform
initialization syntax (braces) allow 'new' to construct records with
list-initialization: "new Point{1, 2}".

Removing this assertion should be perfectly safe; the code here matches
what VisitDeclStmt does for regions allocated on the stack.

This is not activated for any style, might change or go away
completely.

For those that want to play around with it, set
ExperimentalAutoDetectBinPacking to true.

clang-format will then:
Look at whether function calls/declarations/definitions are currently
formatted with one parameter per line (on a case-by-case basis). If so,
clang-format will avoid bin-packing the parameters. If all parameters
are on one line (thus that line is "inconclusive"), clang-format will
make the choice dependent on whether there are other bin-packed
calls/declarations in the same file.

The reason for this change is that bin-packing in some situations can be
really bad and an author might opt to put one parameter on each line. If
the author does that, he might want clang-format not to mess with that.
If the author is unhappy with the one-per-line formatting, clang-format
can easily be convinced to bin-pack by putting any two parameters on the
same line.

Compute mangling numbers for externally visible local variables and tags.
Change the mangler to consistently use discriminators where necessary.
Tweak the scheme we use to number decls which are not externally visible
to avoid unnecessary discriminators in common cases now that we request
them more consistently.

Combined with typo correction's new ability to apply global/absolute nested
name specifiers to possible corrections, cases such as in PR12287 where the
desired function is being shadowed by a lexically closer function with the
same name but a different number of parameters will now include a FixIt.

On a side note, since the test for this change caused
test/SemaCXX/typo-correction.cpp to exceed the typo correction limit for
a single file, I've included a test case for exceeding the limit and added
some comments to both the original and part two of typo-correction.cpp
warning future editors of the files about the limit.

Use UsualArithmeticConversions unconditionally in analysis of
comparisons and conditional operators: the method performs
the usual arithmetic conversions if both sides are arithmetic, and
usual unary conversions if they are not.  This is just a cleanup
for conditional operators; for comparisons, it fixes the issue that
we would try to check isArithmetic() on an atomic type.

Also, fix GetExprRange() in SemaChecking.cpp so it deals with variables
of atomic type correctly.

Fixes PR15537.
