John McCall c07a0c7e48 Change the representation of GNU ?: expressions to use a different expression
class and to bind the shared value using OpaqueValueExpr.  This fixes an
unnoticed problem with deserialization of these expressions where the
deserialized form would lose the vital pointer-equality trait;  or rather,
it fixes it because this patch also does the right thing for deserializing
OVEs.

Change OVEs to not be a "temporary object" in the sense that copy elision is
permitted.

This new representation is not totally unawkward to work with, but I think
that's really part and parcel with the semantics we're modelling here.  In
particular, it's much easier to fix things like the copy elision bug and to
make the CFG look right.

I've tried to update the analyzer to deal with this in at least some          
obvious cases, and I think we get a much better CFG out, but the printing
of OpaqueValueExprs probably needs some work.

NAKAMURA Takumi 31ea2f14bc Triple::MinGW64 is deprecated and removed. We can use Triple::MinGW32 instead.
No one uses *-mingw64. mingw-w64 is represented as {i686|x86_64}-w64-mingw32.

Chandler Carruth 712563bba4 Implement -Wenum-compare, which warns when comparing two enums of
different types. We omit the warning when the enum types are anonymous.
Unlike GCC, this warning does not distinguish between C++ and C/ObjC for
controling whether it is on by default, it is always on by default.

Original patch contributed by Richard Trieu (@ Google), I fixed some
style issues, and cleaned it up for submission.

Duncan Sands e522001171 Transform "A + B >= A + C" into "B >= C" if the adds do not wrap. Likewise for some
variations (some of these were already present so I unified the code).  Spotted by my
auto-simplifier as occurring a lot.

Chris Lattner c8e630e4db Step #1/N of implementing support for __label__: split labels into
LabelDecl and LabelStmt.  There is a 1-1 correspondence between the
two, but this simplifies a bunch of code by itself.  This is because
labels are the only place where we previously had references to random
other statements, causing grief for AST serialization and other stuff.

This does cause one regression (attr(unused) doesn't silence unused
label warnings) which I'll address next.

This does fix some minor bugs:
1. "The only valid attribute " diagnostic was capitalized.
2. Various diagnostics printed as ''labelname'' instead of 'labelname'
3. This reduces duplication of label checking between functions and blocks.

Review appreciated, particularly for the cindex and template bits.

Douglas Gregor b0f2ea9e9e When printing a qualified type, look through a substituted template
parameter type to see what's behind it, so that we don't end up
printing silly things like "float const *" when "const float *" would
make more sense. Also, replace the pile of "isa" tests with a simple
switch enumerating all of the cases, making a few more obvious cases
use prefix qualifiers.

NAKAMURA Takumi 5850225f52 lit/TestingConfig.py: Add the environment variable PRINTF_EXPONENT_DIGITS as workaround [PR6745] for mingw's tests. Danil Malyshev suggested this.
FIXME: It does not improve MSVC's issue.

[Danil Malyshev] Defining PRINTF_EXPONENT_DIGITS env is the suggested way to make MinGW ANSI/POSIX compatible. This is not only about the case we are discussing, but in general, I'd like to have explicitly defined compatibility mode for all the tests running on MinGW.

Johnny Chen 0c64b5bbb6 Refactoring. Wrap the following pseudocode from the ARM Architecture Reference Manul:
// if d == 15 then         // Can only occur for encoding A1
//     ALUWritePC(result); // setflags is always FALSE here
// else
//     R[d] = result;
//     if setflags then
//         APSR.N = result<31>;
//         APSR.Z = IsZeroBit(result);
//         APSR.C = carry;
//         // APSR.V unchanged

into a helper method WriteCoreRegisterWithFlags, and modified the existing methods
to take advantage of it.

Plus add two emulation methods (declaration only for now) for ORR (immediate) and ORR (register).
