(__builtin_* etc.) so that it isn't possible to take their address.
Specifically, introduce a new type to represent a reference to a builtin
function, and a new cast kind to convert it to a function pointer in the
operand of a call. Fixes PR13195.

__objc_yes/__objc_no to (BOOL)1/(BOOL)0 when
BOOL is declared; otherwise it resorts to
default of 'signed char'. This is important to
selecting the correct Numeric API numberWithBool:
Can't have a clang test for this. Will checkin and
executable llvm test. // rdar://12156616

CheckLValueConstantExpression.
Richard pointed out that using the address of a TLS variable is ok in a
core C++11 constant expression, as long as it isn't part of the eventual
result of constant expression evaluation. Having the check in
CheckLValueConstantExpression accomplishes this.

This makes Clang produce an error for code such as:
__thread int x;
int *p = &x;
The lvalue of a thread-local variable cannot be evaluated at compile
time.

We still need to translate the string, but this at least gets us one step
closer to using the more general EmitAsmStmt() codegen function. No functional
change intended.

not be set for implicit instantiations, remove the FIXME. This should be the
last bit for PR13634. The actual fix happened in r162238.
Motivation: it might be misleading to mark implicit instantiations as
Decl::isImplicit = true. Because then, in order to be consistent, we should
mark all instantiated members as implicit. But the user did actually type the
declaration for the member, but the compiler played with it a little bit.

"castAs<...>->doSomething()". The analyzer was flagging these
as potential null dereferences, which is technically true. The
invariants appear to be that these casts should never fail, so
let's use castAs<> instead and avoid a runtime check.

name. This should reduce the amount of warning false positives about bad HTML
in comments when the comment author intended to put a reference to a template.
This change will also enable us parse the comment as intended in these cases.
Fixes part 1 of PR13374.

to overwrite objects that might have been allocated into the type's
tail padding. This patch is missing some potential optimizations where
the destination is provably a complete object, but it's necessary for
correctness.

Add a flag PrintingPolicy::DontRecurseInDeclContext to provide "terse" output
from DeclPrinter. The motivation is to use DeclPrinter to print declarations
in user-friendly format, without overwhelming user with inner detail of the
declaration being printed.
Also add many tests for DeclPrinter. There are quite a few things that we
print incorrectly: search for WRONG in DeclPrinterTest.cpp -- and these tests
check our output against incorrect output, so that we can fix/refactor/rewrite
the DeclPrinter later.
