727b49bc26 Make the GraphRoot edge look like a chain edge, which is more accurate, 
and use the right result number, in the off chance that the graph root
has multiple result values.

8f7b6c8113 Fix a bug in LSR's dead-PHI cleanup. If a PHI has a def-use chain that 
leads into a cycle involving a different PHI, LSR got stuck running
around that cycle looking for the original PHI. To avoid this, keep
track of visited PHIs and stop searching if we see one more than once.
This fixes PR2570.

b024b0eedd Enhance the GraphWriter support for edge destinations, and teach the 
SelectionDAG graph writer to make use of them. Now, nodes with multiple

6e31474e71 Add VerifyNode, a place to put sanity checks on 
generic SDNode's (nodes with their own constructors
should do sanity checking in the constructor).  Add
sanity checks for BUILD_VECTOR and fix all the places
that were producing bogus BUILD_VECTORs, as found by
"make check".  My favorite is the BUILD_VECTOR with
only two operands that was being used to build a
vector with four elements!

ea4a155439 Switch on the use of arbitrary precision integers in scalar evolution. This will 
bail after 256-bits to avoid producing code that the backends can't handle.
Previously, we capped it at 64-bits, preferring to miscompile in those cases.

This change also reverts much of r52248 because the invariants the code was
expecting are now being met.

73f5ecdbea Pull r53795 from Gaz into mainline: 
If .loc and .file aren't used, always emit the "debug_line" section. This
requires at least one entry in the line matrix. So if there's nothing to emit
into the matrix, emit an end of matrix value anyway.

ad24fa3ff4 Make sure custom lowering for LegalizeTypes 
returns a node with the right number of
return values.  This fixes codegen of
Generic/cast-fp.ll, Generic/fp_to_int.ll
and PowerPC/multiple-return-values.ll
when using -march=ppc32 -mattr=+64bit.

852a8f47f1 While testing particular algorithms to compute loop iteration count the brute 
force evaluation (ComputeIterationCountExhaustively) should be turned off.

It doesn't apply to trip-count2.ll because this file tests the brute force
evaluation.

The test for PR2364 (2008-05-25-NegativeStepToZero.ll) currently fails
showing that the patch for this bug doesn't work. I'll fix it in a few hours
with a patch for PR2088.
