Temporary hack to build with GCC 4.0 instead of 4.2.

Use better variable names

Don't use larger alignment.

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!

Use movaps instead of movups to spill 16-byte vector values when default alignment is >= 16. This fixes some massive performance regressions.

Revert r53812 -- premature. LegalizeTypes isn't actually on yet!

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53816 91177308-0d34-0410-b5e6-96231b3b80d8

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.

This header isn't necessary now.

Fix PR2088. Use modulo linear equation solver to compute loop iteration
count.

Fix for first part of PR2562. Generate the "pinsrw" instruction for inserts
into v4i16 vectors.

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.

Unbreak build: 'DarwinTargetAsmInfo' was already taken as PPC TAI flavour.

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.

XFAIL this test.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53793 91177308-0d34-0410-b5e6-96231b3b80d8

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.
