These flags control language options and user-visible macros, so it's
important to preserve them when analyzing. Rather than try to keep up
with all the -f flags, we'll pass them all through and then ban the ones
we don't want (like -fsyntax-only).
-Wwrite-strings is really an f-flag in disguise: it implies -fconst-strings.

Various pieces of code, like base initialization in Sema and RTTI IRGen,
don't properly ignore qualifiers on base classes. Instead of auditing the
whole codebase, just strip them off in the getter. (The type as written is
still available in the TypeSourceInfo for code that cares.)
Fixes PR16596.

This puts a slight penalty on the linebreak before the first "<<", so
that clang-format generally tries to keep things on the first line.
User feedback has shown that this is generally desirable.

& 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.

#if defined(__has_foo("X")) && __has_foo("X")
is not a correct way to portably use __has_foo, because it is expanded to
#if 0 && 0("X")
... which is ill-formed.
Also add a missing ')'.

declarations to inherit the visibility of the prior declaration, rather
than setting a friend declaration to be visible whenever there was a prior
declaration.

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.

use/maintain additional state from the LambdaExpr while visiting the body
of a LambdaExpr.
One use for this arises because Clang's AST currently holds lambda bodies
in a form prior to their adjustment to refer to captured copies of local
variables, and so some clients will need access to the lambda's closure
type in order to query how to map VarDecl*s to the FieldDecls of their
by-copy captures. This hook is sufficient for at least one such client;
to do this without such a hook would require the client to re-implement
the whole of TraverseLambdaExpr, which is non-trivial and would likely be
more brittle.

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.
