Owen Anderson 35bd70c07a Add a test for my previous PRE fix.

Owen Anderson d930420ccf Fix an issue that Chris noticed, where local PRE was not properly instantiating 
a new value numbering set after splitting a critical edge.  This increases
the number of instances of PRE on 403.gcc from ~60 to ~570.

Bill Wendling 30e9dc81c8 Second stab at target-dependent lowering of everyone's favorite nodes: [SU]ADDO 
- LowerXADDO lowers [SU]ADDO into an ADD with an implicit EFLAGS define. The
  EFLAGS are fed into a SETCC node which has the conditional COND_O or COND_C,
  depending on the type of ADDO requested.

- LowerBRCOND now recognizes if it's coming from a SETCC node with COND_O or
  COND_C set.

Douglas Gregor f558618fa4 A little more scaffolding for parsing templates: 
- Template parameter scope to hold the template parameters
  - Template parameter context for parsing declarators
  - Actions for template type parameters and non-type template
    parameters

Fariborz Jahanian 015a48d1db This patch corrects problem in searching for a setter/getter method for 
a property. Previous scheme of seaching in interface's list of methods
would not work because this list is not yet constructed. This is in preparation
for doing semantic check on viability of setter/getter method declarations.

Dale Johannesen 069a4eee55 Consider only references to an IV within the loop when 
figuring out the base of the IV.  This produces better
code in the example.  (Addresses use (IV) instead of 
(BASE,IV) - a significant improvement on low-register
machines like x86).

Scott Michel 08a4e2045d CellSPU: 
- Fix v2[if]64 vector insertion code before IBM files a bug report.
- Ensure that zero (0) offsets relative to $sp don't trip an assert
  (add $sp, 0 gets legalized to $sp alone, tripping an assert)
- Shuffle masks passed to SPUISD::SHUFB are now v16i8 or v4i32

Chris Lattner 2bc97759b3 define array_pod_sort in terms of operator< instead of my brain 
damaged approximation.  This should fix it on big endian platforms

Duncan Sands 3d960941b1 There are no longer any places that require a 
MERGE_VALUES node with only one operand, so get
rid of special code that only existed to handle
that possibility.

Duncan Sands 6ed40141f7 Change the interface to the type legalization method 
ReplaceNodeResults: rather than returning a node which
must have the same number of results as the original
node (which means mucking around with MERGE_VALUES,
and which is also easy to get wrong since SelectionDAG
folding may mean you don't get the node you expect),
return the results in a vector.

Chris Lattner 2c2dd15a85 Introduce a new array_pod_sort function and switch LSR to use it 
instead of std::sort.  This shrinks the release-asserts LSR.o file
by 1100 bytes of code on my system.

We should start using array_pod_sort where possible.
