LowerSubregs pass. Add a new TII, subreg_to_reg, which is like insert_subreg except that it takes an immediate implicit value to insert into rather than a register.

the type instead of the byte size. This was causing troublesome mis-compilations.
True to form, this took 2 days to find and is a one-line fix. :-P

on real instructions, ridding the asm printers of the hack used to do this previously. In the process, update LowerSubregs to be careful about eliminating copies that have side affects.
Note: the coalescer will have to be careful about this too, when it starts coalescing insert_subreg nodes.

Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.
This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.

calls here. This was done earlier for params in
the varargs part of the params; any float params
that survive to here are in the non-varargs part,
and must not be promoted.

function livein's. Take 2008-03-10-RegAllocInfLoop.ll, the schedule looks like this after these copies are inserted:
entry: 0x12049d0, LLVM BB @0x1201fd0, ID#0:
Live Ins: %EAX %EDX %ECX
%reg1031<def> = MOVPC32r 0
%reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def>
%reg1028<def> = MOV32rr %EAX
%reg1029<def> = MOV32rr %EDX
%reg1030<def> = MOV32rr %ECX
%reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x1201910 + 0]
%reg1025<def> = MOV32rr %reg1029
%reg1026<def> = MOV32rr %reg1030
%reg1024<def> = MOV32rr %reg1028
The copies unnecessarily increase register pressure and it will end up requiring a physical register to be spilled.
With -schedule-livein-copies:
entry: 0x12049d0, LLVM BB @0x1201fa0, ID#0:
Live Ins: %EAX %EDX %ECX
%reg1031<def> = MOVPC32r 0
%reg1032<def> = ADD32ri %reg1031, <es:_GLOBAL_OFFSET_TABLE_>, %EFLAGS<imp-def>
%reg1024<def> = MOV32rr %EAX
%reg1025<def> = MOV32rr %EDX
%reg1026<def> = MOV32rr %ECX
%reg1027<def> = MOV8rm %reg0, 1, %reg0, 0, Mem:LD(1,1) [0x12018e0 + 0]
Much better!

the fcopysign expansion from LegalizeDAG to get rid of
what seems to be a bug: the use of sign extension means
that when copying the sign bit from an f32 to an f64,
the upper 32 bits of the f64 (now an i64) are set, not
just the top bit... I also generalized it to work for
any sized floating point types, and removed the bogosity:
SDOperand Mask1 = (SrcVT == MVT::f64)
? DAG.getConstantFP(BitsToDouble(1ULL << 63), SrcVT)
: DAG.getConstantFP(BitsToFloat(1U << 31), SrcVT);
Mask1 = DAG.getNode(ISD::BIT_CONVERT, SrcNVT, Mask1);
(here SrcNVT is an integer with the same size as SrcVT).
As far as I can see this takes a 1 << 63, converts to
a double, converts that to a floating point constant
then converts that to an integer constant, ending up
with... 1 << 63 as an integer constant! So I just
generate this integer constant directly.
