The TargetPassManager's default constructor wants to initialize the PassManager
to 'null'. But it's illegal to bind a null reference to a null l-value. Make the
ivar a pointer instead.

Replace some assert() calls w/ actual diagnostics. In a perfect world,
there'd be range checks on these values long before things ever reached
this code. For now, though, issuing a better-late-than-never diagnostic
is still a big improvement over assert().

This was exposed by SingleSource/UnitTests/Vector/constpool.c.
The computed size of a basic block isn't always a multiple of its known
alignment, and that can introduce extra alignment padding after the
block.

On x86-32, structure return via sret lets the callee pop the hidden
pointer argument off the stack, which the caller then re-pushes.
However if the calling convention is fastcc, then a register is used
instead, and the caller should not adjust the stack. This is
implemented with a check of IsTailCallConvention
X86TargetLowering::LowerCall but is now checked properly in
X86FastISel::DoSelectCall.

ARM BUILD_VECTORs created after type legalization cannot use i8 or i16
operands, since those types are not legal. Instead use i32 operands, which
will be implicitly truncated by the BUILD_VECTOR to match the element type.

Previously, ARMConstantIslandPass would conservatively compute the
address of an aligned basic block as:
RoundUpToAlignment(Offset + UnknownPadding)
This worked fine for the layout algorithm itself, but it could fool the
verify() function because it accounts for alignment padding twice: Once
when adding the worst case UnknownPadding, and again by rounding up the
fictional block offset. This meant that when optimizeThumb2Instructions
would shrink an instruction, the conservative distance estimate could
grow. That shouldn't be possible since the woorst case alignment padding
wss already included.
This patch drops the use of RoundUpToAlignment, and depends only on
worst case padding to compute conservative block offsets. This has the
weird effect that the computed offset for an aligned block may not be
aligned.
The important difference is that shrinking an instruction can never
cause the estimated distance between two instructions to grow. The
estimated distance is always larger than the real distance that only the
assembler knows.

* Model FPSW (the FPU status word) as a register.
* Add ISel patterns for the FUCOM*, FNSTSW and SAHF instructions.
* During Legalize/Lowering, build a node sequence to transfer the comparison
result from FPSW into EFLAGS. If you're wondering about the right-shift: That's
an implicit sub-register extraction (%ax -> %ah) which is handled later on by
the instruction selector.
