When we run into an error parsing or type-checking the left-hand side
...
of a binary expression, continue on and parse the right-hand side of
the binary expression anyway, but don't call the semantic actions to
type-check. Previously, we would see the error and then, effectively,
skip tokens until the end of the statement.
The result should be more useful recovery, both in the normal case
(we'll actually see errors beyond the first one in a statement), but
it also helps code completion do a much better job, because we do
"real" code completion on the right-hand side of an invalid binary
expression rather than completing with the recovery completion. For
example, given
x = p->y
if there is no variable named "x", we can still complete after the p->
as a member expression. Along the recovery path, we would have
completed after the "->" as if we were in an expression context, which
is mostly useless.

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.

Truncate block variable of bool type to i1 when its
...
value is used. This matches with non-block variable
use of bool type. (Fixes radar 8390062).

Add symantic support for the Pascal calling convention via
...
"__attribute((pascal))" or "__pascal" (and "_pascal" under
-fborland-extensions). Support still needs to be added to llvm.

Get rid of the "functions declared 'noreturn' should have a 'void' result type" warning.
...
The rationale behind this is that it is normal for callback functions to have a non-void return type
and it should still be possible to mark them noreturn. (JavaScriptCore is a good example of this).
