Douglas Gregor e81f58e180 Properly diagnose invalid casts to function references. Patch by
Faisal Vali, tweaked by me. Fixes PR8230.

Chris Lattner 53fa04909c make clang print types as "const int *" instead of "int const*",
which is should have done from the beginning.  As usual, the most
fun with this sort of change is updating all the testcases.

John McCall 3155f573f5 Turn access control on by default in -cc1.
Remove -faccess-control from -cc1; add -fno-access-control.
Make the driver pass -fno-access-control by default.
Update a bunch of tests to be correct under access control.

Douglas Gregor deb714ceeb Switch static_cast from the old reference-initialization code (via
CheckReferenceInit) over to the new initialization code
(InitializationSequence), which is better-tested and doesn't require
us to compute the entire conversion sequence twice.

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

Douglas Gregor c934bc840c Perform overload resolution when static_cast'ing from a
pointer-to-member-to-derived to a pointer-to-member-to-base. Fixes
PR6072.

John McCall 5b0829a321 Improve access control diagnostics. Perform access control on member-pointer
conversions.  Fix an access-control bug where privileges were not considered
at intermediate points along the inheritance path.  Prepare for friends.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor 8f3952cda9 When performing a static downcast as part of a static_cast, make sure
that we're dealing with canonical types like the documentation say
(yay, CanQualType). Alas, this is another instance where using
getQualifiers() on a non-canonical QualType got us in trouble.

Good news: with this fix, Clang can now parse all of its own headers!

Sebastian Redl 7c353685bc - Have TryStaticImplicitCast set the cast kind to NoOp when binding a reference. CheckReferenceInit already inserts implicit casts to the necessary types. This fixes an assertion in CodeGen for some casts and brings a fix for PR5453 close, if I understand that bug correctly.
- Also, perform calculated implicit cast sequences if they're determined to work. This finally diagnoses static_cast to ambiguous or implicit bases and fixes two long-standing fixmes in the test case. For the C-style cast, this requires propagating the access check suppression pretty deep into other functions.
- Pass the expressions for TryStaticCast and TryStaticImplicitCast by reference. This should lead to a better AST being emitted for such casts, and also fixes a memory leak, because CheckReferenceInit and PerformImplicitConversion wrap the node passed to them. These wrappers were previously lost.

Douglas Gregor bf3f322034 When type-checking a static cast (or the static_cast part of a C-style
cast) that is converting to a class type, enumerate its constructors
as in any other direct initialization. This ensures that we get the
proper conversion sequence.

Sebastian Redl 9f831dbbcd Implement C++ semantics for C-style and functional-style casts. This regresses Clang extension conversions, like vectors, but allows conversions via constructors and conversion operators.
Add custom conversions to static_cast.

Sebastian Redl ed8f200318 Implement pointer to member handling in static_cast.

Make a few style corrections as suggested by Chris.
