...
In that patch I added a bogus type promotion for unary '!'.
The real bug was more fallout from edges cases with compound assignments and conjured symbolic values. Now the conjured value has the type of the LHS expression, and we do a promotion to the computation type. We also now correctly do a conversion from the computation type back to the LHS type.

Add a new expression node, CXXOperatorCallExpr, which expresses a
...
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)
I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

2. In do/while parsing, don't require a 'while' to be present if the do
body didn't parse.
This allows us to generate a clean diagnostic for this code:
t.c:1:22: error: expected expression
void foo (void) { do . while (0); }

Backout of r59196, plus a new ICE test. Sorry if this is a
...
little rude; I figure it's cleaner to just back this out now so
it doesn't get forgotten or mixed up with other checkins.
The modification to isICE is simply wrong; I've added a test that the
change to isICE breaks.
I'm pretty sure the modification to tryEvaluate is also wrong.
At the very least, there's some serious miscommunication going on here,
as this is going in exactly the opposite direction of r59105. My
understanding is that tryEvaluate is not supposed to care about side
effects. That said, a lot of the clients to tryEvaluate are
expecting it to enforce a no-side-effects policy, so we probably need
another method that provides that guarantee.

Implement support for operator overloading using candidate operator
...
functions for built-in operators, e.g., the builtin
bool operator==(int const*, int const*)
can be used for the expression "x1 == x2" given:
struct X {
operator int const*();
} x1, x2;
The scheme for handling these built-in operators is relatively simple:
for each candidate required by the standard, create a special kind of
candidate function for the built-in. If overload resolution picks the
built-in operator, we perform the appropriate conversions on the
arguments and then let the normal built-in operator take care of it.
There may be some optimization opportunity left: if we can reduce the
number of built-in operator overloads we generate, overload resolution
for these cases will go faster. However, one must be careful when
doing this: GCC generates too few operator overloads in our little
test program, and fails to compile it because none of the overloads it
generates match.
Note that we only support operator overload for non-member binary
operators at the moment. The other operators will follow.
As part of this change, ImplicitCastExpr can now be an lvalue.

Some additions to tryEvaluate I've had sitting around for a while.
...
This pushes it a lot closer to being able to deal with most of the stuff
CodeGen's constant expression evaluator knows how to deal with. This
also fixes PR3003.
The test could possibly use some improvement, but this'll work for now.
Test 6 is inspired by PR3003; the other tests are mostly just designed
to exercise the new code. The reason for the funny structure of the
tests is that type fixing for arrays inside of structs is the only place
in Sema that calls tryEvaluate, at least for the moment.

IRgen improvements on unreachable code:
...
- Split out "simple" statements which can easily handle IR generation
when there is no insert point. These are generally statements which
start by emitting a new block or are only containers for other
statements.
- This fixes a regression in emitting dummy blocks, notably for case
statements.
- This also fixes spurious emission of a number of debug stoppoint
intrinsic instructions.
Remove unneeded sw.body block, just clear the insertion point.
Lift out CodeGenFunction::EmitStopPoint which calls into the
CGDebugInfo class when generating debug info.
Normalize definitions of Emit{Break,Continue}Stmt and usage of
ErrorUnsupported.

Make emission of 'if' conditions much more sophisticated when we
...
have a condition that is an &&/||. Before we used to compile things like this:
int test() {
if (x && y) foo(); else bar();
}
into:
%0 = load i32* @x ; <i32> [#uses=1]
%1 = icmp ne i32 %0, 0 ; <i1> [#uses=1]
br i1 %1, label %land_rhs, label %land_cont
land_rhs: ; preds = %entry
%2 = load i32* @y ; <i32> [#uses=1]
%3 = icmp ne i32 %2, 0 ; <i1> [#uses=1]
br label %land_cont
land_cont: ; preds = %land_rhs, %entry
%4 = phi i1 [ false, %entry ], [ %3, %land_rhs ] ; <i1> [#uses=1]
br i1 %4, label %ifthen, label %ifelse
ifthen: ; preds = %land_cont
%call = call i32 (...)* @foo() ; <i32> [#uses=0]
br label %ifend
ifelse: ; preds = %land_cont
%call1 = call i32 (...)* @bar() ; <i32> [#uses=0]
br label %ifend
ifend: ; preds = %ifelse, %ifthen
Now we turn it into the much more svelte code:
%0 = load i32* @x ; <i32> [#uses=1]
%1 = icmp ne i32 %0, 0 ; <i1> [#uses=1]
br i1 %1, label %land_lhs_true, label %ifelse
land_lhs_true: ; preds = %entry
%2 = load i32* @y ; <i32> [#uses=1]
%3 = icmp ne i32 %2, 0 ; <i1> [#uses=1]
br i1 %3, label %ifthen, label %ifelse
ifthen: ; preds = %land_lhs_true
%call = call i32 (...)* @foo() ; <i32> [#uses=0]
br label %ifend
ifelse: ; preds = %land_lhs_true, %entry
%call1 = call i32 (...)* @bar() ; <i32> [#uses=0]
br label %ifend
ifend: ; preds = %ifelse, %ifthen
Note the lack of a phi node.

Rework IRgen invariant w.r.t. current insert point.
...
- EmitStmt is no longer required to finish with a current insertion
point defined (i.e. it does not need to make dummy
blocks). Instead, it can clear the insertion point in the builder
which indicates that the current insertion point is unreachable.
- CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint
which respectively test if there is an insert point and ensure an
insertion point exists (by making a dummy block).
- Clearly mark functions in CodeGenFunction which can be called with
no insertion point defined. Currently this is a limited set, and
EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR.
Remove EmitDummyBlock, which is no longer needed. Clients who haven't
already cleared the insertion point (typically via EmitBranch) can do
so by hand.
Remove isDummyBlock, which has effectively been renamed to
HaveInsertPoint.
The main thrust of this change is that we no longer have create dummy
blocks just to destroy them a short time later in EmitBlock in the
common case that there is no unreachable code following something like
a goto.
Additionally, this means that we are not using the hokey condition in
isDummyBlock that a block without a name is a dummy block. Guess how
well that works when we never emit block names!

Introduce annotation tokens, a special kind of token, created and used only by the parser to replace a group of tokens with a single token encoding semantic information.

Will be fully utilized later for C++ nested-name-specifiers.

Parsing, ASTs, and semantic analysis for the declaration of conversion

functions in C++, e.g.,
struct X {
operator bool() const;

Note that these conversions don't actually do anything, since we don't
yet have the ability to use them for implicit or explicit conversions.
