d038e04188 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!

2ceb40f3da 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.

fbbd701bbd 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.

5c779a46b0 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.

77926da196 Revert 53729, after waking up in the middle of 
the night realising that it was wrong :)  I
think the reason the same type was being used
for the shufflevec of indices as for the actual
indices is so that if one of them needs splitting
then so does the other.  After my patch it might
be that the indices need splitting but not the
rest, yet there is no good way of handling that.
I think the right solution is to not have the
shufflevec be an operand at all: just have it
be the list of numbers it actually is, stored
as extra info in the node.
