Move getAccessedFieldNo out of lib/AST/Expr.cpp into

lib/CodeGen/CGExpr.cpp and to change include/clang/AST/Attr.h to
use its own enum for visibility types instead of using
llvm::GlobalValue::VisibilityTypes. These changes eliminate
dependencies in the AST library on LLVM's VMCore library.

multiple times.)

Fix the emission of expressions like char a[10] = "asdf"; previously,
...
they were causing bad code to be emitted. There are two fixes here: one
makes sure we emit a string that is long enough, and one makes sure we
properly handle string initialization in init lists.

f2442dcc8d
Fix support for _Bool bitfields. The issue is that the bitfield width
...
used for _Bool is not the same as the primitive width (which for _Bool
is 1 bit). The load and store changes add some casts to make the
types consistent. The EmitLValue changes make sure that the pointer is
of an appropriate type for loading the bitfield.
This isn't perfect, but it's an improvement, and getting everything
right depends on actually laying out structs in an ABI-compliant way.

Extend vector member references to include {.hi, .lo, .e, .o} which return a
...
vector of the same element type and half the width, with the high, low, even,

Allow member references to member references, so that .hi.hi gives you the high
quarter of a vector. This is fairly convenient syntax for some insert/extract
operations.
Remove some unnecessary methods/types in the ExtVectorElementExpr class.

This is a fairly mechanical/large change. As a result, I avoided making any changes/simplifications that weren't directly related. I did break two Analysis tests.
