Chris Lattner ea952f05a5 fix the code that infers SV info to be correct when dealing
with an indexed load/store that has an offset in the index.

Jakob Stoklund Olesen 1ccded77c0 Add LiveInterval::find and use it for most LiveRange searching operations
instead of calling lower_bound or upper_bound directly.

This cleans up the search logic a bit because {lower,upper}_bound compare
LR->start by default, and it is usually simpler to search LR->end.

Funnelling all searches through one function also makes it possible to replace
the search algorithm with something faster than binary search.

Chris Lattner 82fd06d3ce it's more elegant to put the "getConstantPool" and
"getFixedStack" on the MachinePointerInfo class.  While
this isn't the problem I'm setting out to solve, it is the
right way to eliminate PseudoSourceValue, so lets go with it.

Chris Lattner c3e05d6e50 update the X86 backend to use the MachinePointerInfo version of one
of the getLoad methods.  This fixes at least one bug where an incorrect
svoffset is passed in (a potential combiner-aa miscompile).

Sean Callanan fc55f5d1b0 Removed the hacky "#define this ___clang_this" handler
for C++ classes.  Replaced it with a less hacky approach:

 - If an expression is defined in the context of a
   method of class A, then that expression is wrapped as
   ___clang_class::___clang_expr(void*) { ... }
   instead of ___clang_expr(void*) { ... }.

 - ___clang_class is resolved as the type of the target
   of the "this" pointer in the method the expression
   is defined in.

 - When reporting the type of ___clang_class, a method
   with the signature ___clang_expr(void*) is added to
   that class, so that Clang doesn't complain about a
   method being defined without a corresponding
   declaration.

 - Whenever the expression gets called, "this" gets
   looked up, type-checked, and then passed in as the
   first argument.

This required the following changes:

 - The ABIs were changed to support passing of the "this"
   pointer as part of trivial calls.

 - ThreadPlanCallFunction and ClangFunction were changed
   to support passing of an optional "this" pointer.

 - ClangUserExpression was extended to perform the
   wrapping described above.

 - ClangASTSource was changed to revert the changes
   required by the hack.

 - ClangExpressionParser, IRForTarget, and
   ClangExpressionDeclMap were changed to handle
   different manglings of ___clang_expr flexibly.  This
   meant no longer searching for a function called
   ___clang_expr, but rather looking for a function whose
   name *contains* ___clang_expr.

 - ClangExpressionParser and ClangExpressionDeclMap now
   remember whether "this" is required, and know how to
   look it up as necessary.

A few inheritance bugs remain, and I'm trying to resolve
these.  But it is now possible to use "this" as well as
refer implicitly to member variables, when in the proper
context.
