Simplify array bound checks and clarify comments.  One element array can have same non-zero number as lower bound as well as upper bound.

Fix various things in the instruction emulation code:

    - Add ability to control whether or not the emulator advances the
    PC register (in the emulation state), if the instruction itself
    does not change the pc value..

    - Fix a few typos in asm description strings.

    - Fix bug in the carry flag calculation.

Start overhauling static analyzer support for C++ constructors.  The inlining support isn't complete, and needs
to be reworked to model CallEnter/CallExit (just like all other calls).  For now, treat constructors mostly
like other function calls, making the analysis of C++ code just a little more useful.

Do not use zero as an upper bound for unbounded array because upper bound zero also indicates one element array. 

llvm-svn: 129157

If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.

The previous cleanup of LDRD got overzealous and removed it, causing post-RA
scheduling to get overzealous in breaking antidependencies and invalidate these instructions. Hilarity and invalid assembly ensued.

This patch authored by Eric Niebler.

Many methods on the Sema class (e.g. ConvertPropertyForRValue) take Expr
pointers as in/out parameters (Expr *&).  This is especially true for the
routines that apply implicit conversions to nodes in-place.  This design is
workable only as long as those conversions cannot fail.  If they are allowed
to fail, they need a way to report their failures.  The typical way of doing
this in clang is to use an ExprResult, which has an extra bit to signal a
valid/invalid state.  Returning ExprResult is de riguour elsewhere in the Sema
interface.  We suggest changing the Expr *& parameters in the Sema interface
to ExprResult &.  This increases interface consistency and maintainability.

This interface change is important for work supporting MS-style C++
properties.  For reasons explained here
<http://lists.cs.uiuc.edu/pipermail/cfe-dev/2011-February/013180.html>,
seemingly trivial operations like rvalue/lvalue conversions that formerly
could not fail now can.  (The reason is that given the semantics of the
feature, getter/setter method lookup cannot happen until the point of use, at
which point it may be found that the method does not exist, or it may have the
wrong type, or overload resolution may fail, or it may be inaccessible.)
