Duncan Sands b56334b4f2 While this test is testing a problem in the generic part of codegen, 
the problem only shows for msp430 and pic16 which is why it specifies
them using -march.  But it is wrong to put such tests in CodeGen/Generic,
since not everyone builds these targets.  Put a copy of the test in each
of the target test directories.

Dale Johannesen 5ece8f0a20 Do not store R31 into the caller's link area on PPC. 
This violates the ABI (that area is "reserved"), and
while it is safe if all code is generated with current
compilers, there is some very old code around that uses
that slot for something else, and breaks if it is stored
into.  Adjust testcases looking for current behavior.
I've verified that the stack frame size is right in all
testcases, whether it changed or not.  7311323.

Anton Korobeynikov 2522908653 Materialize global addresses via movt/movw pair, this is always better 
than doing the same via constpool:
1. Load from constpool costs 3 cycles on A9, movt/movw pair - just 2.
2. Load from constpool might stall up to 300 cycles due to cache miss.
3. Movt/movw does not use load/store unit.
4. Less constpool entries => better compiler performance.

This is only enabled on ELF systems, since darwin does not have needed
relocations (yet).

a valid target type correctly (PPC).

Duncan Sands cc0a0cb4b7 Fix PR5558, which was caused by a wrong fix for PR3393 (see commit 63048), 
which was an expensive checks failure due to a bug in the checking.  This
patch in essence reverts the original fix for PR3393, and refixes it by a
tweak to the way expensive checking is done.

Bruno Cardoso Lopes 4713b282ce - Add sugregister logic to handle f64=(f32,f32).

Instead of:
  sdc $f0, X($3)
Generate:
  swc $f0, X($3)
  swc $f1, X+4($3)

Bob Wilson 108aadf972 Tail duplication still needs to iterate. Duplicating new instructions onto

Jakob Stoklund Olesen 575c3f3d72 Fix PR5300. 
When TwoAddressInstructionPass deletes a dead instruction, make sure that all

Jakob Stoklund Olesen fffff88a3c Enable -split-phi-edges by default, except when -regalloc=local. 
The local register allocator doesn't like it when LiveVariables is run.
We should also disable edge splitting under -O0, but that has to wait a bit.
