Dan Gohman c8d2b0135a Don't set neverHasSideEffects on x86's divide instructions, since
they trap on divide-by-zero, and this side effect is otherwise
unmodeled.

Duncan Sands 3ca78c675e Remove integer promotion support for FP_EXTEND
and FP_ROUND.  Not sure what these were doing
here - probably they were sometimes (wrongly)
created with integer operands somewhere that
has since been fixed.

Steve Naroff 119f60e12a Fix <rdar://problem/6329769> [sema] crash on duplication definition of interface with protocols.
As soon as we detect duplicate interfaces, discontinue further semantic checks (returning the original interface).

This is now consistent with how we handle protocols (and less error prone in general).

Nick Lewycky 1c451ae43e Add a utility function that detects whether a loop is guaranteed to be finite.
Use it to safely handle less-than-or-equals-to exit conditions in loops. These
also occur when the loop exit branch is exit on true because SCEV inverses the
icmp predicate.

Use it again to handle non-zero strides, but only with an unsigned comparison
in the exit condition.

Douglas Gregor 4ea8043d6f As threatened previously: consolidate name lookup and the creation of
DeclRefExprs and BlockDeclRefExprs into a single function
Sema::ActOnDeclarationNameExpr, eliminating a bunch of duplicate
lookup-name-and-check-the-result code.

Note that we still have the three parser entry points for identifiers,
operator-function-ids, and conversion-function-ids, since the parser
doesn't (and shouldn't) know about DeclarationNames. This is a Good
Thing (TM), and there will be more entrypoints coming (e.g., for C++
pseudo-destructor expressions).

Douglas Gregor 163c58502a Extend DeclarationName to support C++ overloaded operators, e.g.,
operator+, directly, using the same mechanism as all other special
names.

Removed the "special" identifiers for the overloaded operators from
the identifier table and IdentifierInfo data structure. IdentifierInfo
is back to representing only real identifiers.

Added a new Action, ActOnOperatorFunctionIdExpr, that builds an
expression from an parsed operator-function-id (e.g., "operator
+"). ActOnIdentifierExpr used to do this job, but
operator-function-ids are no longer represented by IdentifierInfo's.

Extended Declarator to store overloaded operator names. 
Sema::GetNameForDeclarator now knows how to turn the operator
name into a DeclarationName for the overloaded operator. 

Except for (perhaps) consolidating the functionality of
ActOnIdentifier, ActOnOperatorFunctionIdExpr, and
ActOnConversionFunctionExpr into a common routine that builds an
appropriate DeclRefExpr by looking up a DeclarationName, all of the
work on normalizing declaration names should be complete with this
commit.

Chris Lattner 6d29c10564 Change a couple of the Parser::Diag methods to return DiagnosticInfo
and let the clients push whatever they want into the DiagnosticInfo
instead of hard coding a few forms.  Also switch various clients to
use Diag(Tok, ...) instead of Diag(Tok.getLocation(), ...) as the
canonical form to simplify the code a bit.

Chris Lattner 8488c8297c This reworks some of the Diagnostic interfaces a bit to change how diagnostics
are formed.  In particular, a diagnostic with all its strings and ranges is now
packaged up and sent to DiagnosticClients as a DiagnosticInfo instead of as a 
ton of random stuff.  This has the benefit of simplifying the interface, making
it more extensible, and allowing us to do more checking for things like access
past the end of the various arrays passed in.

In addition to introducing DiagnosticInfo, this also substantially changes how 
Diagnostic::Report works.  Instead of being passed in all of the info required
to issue a diagnostic, Report now takes only the required info (a location and 
ID) and returns a fresh DiagnosticInfo *by value*.  The caller is then free to
stuff strings and ranges into the DiagnosticInfo with the << operator.  When
the dtor runs on the DiagnosticInfo object (which should happen at the end of
the statement), the diagnostic is actually emitted with all of the accumulated
information.  This is a somewhat tricky dance, but it means that the 
accumulated DiagnosticInfo is allowed to keep pointers to other expression 
temporaries without those pointers getting invalidated.

This is just the minimal change to get this stuff working, but this will allow
us to eliminate the zillions of variant "Diag" methods scattered throughout
(e.g.) sema.  For example, instead of calling:

  Diag(BuiltinLoc, diag::err_overload_no_match, typeNames,
       SourceRange(BuiltinLoc, RParenLoc));

We will soon be able to just do:

  Diag(BuiltinLoc, diag::err_overload_no_match)
      << typeNames << SourceRange(BuiltinLoc, RParenLoc));

This scales better to support arbitrary types being passed in (not just 
strings) in a type-safe way.  Go operator overloading?!
