Chris Lattner 1ca2068227 realize that instructions who match intrinsics that read memory read memory.
Also, instructions with any nodes that are SDNPMayLoad also read memory.

Chris Lattner d2cdb97747 Ted apparently likes crazy whitespace at the end of line. Crush his spirit by
removing them, fitting the file into 80 columns. :)

Owen Anderson 4f45cef2f9 Get rid of all uses of LiveVariables::VarInfo::DefInst in favor of the equivalent API from
MachineRegisterInfo.  Once all clients are switched over, the former will be going away.

Chris Lattner cb0e1bcf0c provide def_* and use_* iterators in addition to reg_* iterators.
The first only returns definitions of a register, the second only
returns uses, the third returns both.

Evan Cheng fead113fe0 Do not use the stack pointer directly, issue a copyfromreg instead. Otherwise we can end up with something like ADD32ri %esp, x which two-address pass won't like.

Chris Lattner ec79bba97f Fix PR1845 and rdar://5676945. Generic vectors smaller
than hardware supported type will be scalarized, so we
can infer their alignment from that info.

We now codegen pr1845 into:

_boolVectorSelect:
	lbz r2, 0(r3)
	stb r2, -16(r1)
	blr

Steve Naroff e6b0ec8b5e Fix Sema::ActOnDeclarator() to call MergeFunctionDecl for function decls that aren't in scope. Since C functions are in a flat namespace, we need to give them special treatment (when compared with variables and typedefs).

Ted Kremenek 24ea11d4e0 Renamed various traits and classes. Added "Infeasible" bit to ExplodedNodeImpl
so that nodes can be marked as representing an infeasible program point. This
flag lets the path-sensitive solver know that no successors should be generated
for such nodes.

Ted Kremenek 84ab850e46 Renamed Stmt***Edge and ***StmtEdge (where *** = "Stmt" or "Blk") classes to
BExpr*** and ***BExpr respectively. These edges represent program locations
between the entrance/exit of a block and Block-level Expressions.

Also added ***SExpr and SExpr*** ProgramEdges to represent the locations in the
program between the evaluation of subexpressions and block-level expressions.

Chris Lattner 119d81a4f4 Fix isIntegerConstantExpr to compare against zero for casts to bool instead of
truncating.  This allows us to compile:
 void foo() {
  static _Bool foo = 4;
}

into:
@foo1 = internal global i8 1
instead of:
@foo1 = internal global i8 4
