Bill Wendling a7912f8894 Remove the final bits of Attributes being declared in the Attribute
namespace. Use the attribute's enum value instead. No functionality change
intended.

Richard Smith 683398a3b6 -fcatch-undefined-behavior: store the type name directly at the end of a type descriptor. 5% binary size reduction due to fewer relocations.

Richard Smith 639b8d05dd When a bad UTF-8 encoding or bogus escape sequence is encountered in a
string literal, produce a diagnostic pointing at the erroneous character
range, not at the start of the literal.

Richard Smith 4d1458ed38 -fcatch-undefined-behavior: Factor emission of the creation of, and branch to,
the trap BB out of the individual checks and into a common function, to prepare
for making this code call into a runtime library. Rename the existing EmitCheck
to EmitTypeCheck to clarify it and to move it out of the way of the new
EmitCheck.

Eli Friedman 34866c7719 Change the representation of builtin functions in the AST
(__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.

Richard Smith 69d0d2626a New -fcatch-undefined-behavior features:
* when checking that a pointer or reference refers to appropriate storage for a type, also check the alignment and perform a null check
 * check that references are bound to appropriate storage
 * check that 'this' has appropriate storage in member accesses and member function calls

John McCall 8dda7b27ee Distinguish more carefully between free functions and C++ instance methods
in the ABI arrangement, and leave a hook behind so that we can easily
tweak CCs on platforms that use different CCs by default for C++
instance methods.

John McCall 4e8ca4fa14 Significantly simplify CGExprAgg's logic about ignored results:
if we want to ignore a result, the Dest will be null.  Otherwise,
we must copy into it.  This means we need to ensure a slot when
loading from a volatile l-value.

With all that in place, fix a bug with chained assignments into
__block variables of aggregate type where we were losing insight into
the actual source of the value during the second assignment.

Nico Weber 3a691a367c Support L__FUNCTION__ in microsoft mode, PR11789
Heavily based on a patch from
Aaron Wishnick <aaron.s.wishnick@gmail.com>.

I'll clean up the duplicated function in CodeGen as
a follow-up, later today or tomorrow.
