new DiagnoseIncompleteType. It provides additional information about
struct/class/union/enum types when possible, either by pointing to the
forward declaration of that type or by pointing to the definition (if
we're in the process of defining that type). 
Fixes <rdar://problem/6500531>.

DIVREM isel deficiency: If sign bit is known zero, zero out DX/EDX/RDX instead of sign extending the low part (in AX/EAX/RAX) into it.

   code, but no sense trying too hard since ccc will be moved to

The way this worked before was to test APInt by running
"lli -force-interpreter=true" knowing the lli uses APInt under the hood to
store its values. Now, we test APInt directly.

Minor tweak to LowerUINT_TO_FP_i32. Bias (after scalar_to_vector) has two uses so we should make it the second source operand of ISD::OR so 2-address pass won't have to be smart about commuting.

%reg1024<def> = MOVSDrm %reg0, 1, %reg0, <cp#0>, Mem:LD(8,8) [ConstantPool + 0]
%reg1025<def> = MOVSD2PDrr %reg1024
%reg1026<def> = MOVDI2PDIrm <fi#-1>, 1, %reg0, 0, Mem:LD(4,16) [FixedStack-1 + 0]
%reg1027<def> = ORPSrr %reg1025<kill>, %reg1026<kill>
%reg1028<def> = MOVPD2SDrr %reg1027<kill>
%reg1029<def> = SUBSDrr %reg1028<kill>, %reg1024<kill>
%reg1030<def> = CVTSD2SSrr %reg1029<kill>
MOVSSmr <fi#0>, 1, %reg0, 0, %reg1030<kill>, Mem:ST(4,4) [FixedStack0 + 0]
%reg1031<def> = LD_Fp32m80 <fi#0>, 1, %reg0, 0, Mem:LD(4,16) [FixedStack0 + 0]
RET %reg1031<kill>, %ST0<imp-use,kill>

The reason 2-addr pass isn't smart enough to commute the ORPSrr is because it can't look pass the MOVSD2PDrr instruction.

optimize it to a SINT_TO_FP when the sign bit is known zero. X86 isel should perform the optimization itself.

we assumed a CFG structure that would be valid when all code in 
the function is reachable, but not all code is necessarily 
reachable.  Do a simple, but horrible, CFG walk to check for this
case.

because of dead code, a phi could use the speculated instruction
that was not in "BB2".  Make this check explicit and tighten up 
some other corners.  This fixes PR3292.  No testcase becauase this
depends entirely on visitation order of blocks and requires a 
sequence of 8 passes to repro.
