Turn floating point IVs into integer IVs where possible.
This allows SCEV users to effectively calculate trip count.
LSR later on transforms back integer IVs to floating point IVs
later on to avoid int-to-float casts inside the loop.

Refactor various TargetAsmInfo subclasses' TargetMachine members away
adding a TargetMachine member to the base TargetAsmInfo class instead.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58624 91177308-0d34-0410-b5e6-96231b3b80d8

Change how extended types are represented in MVTs. Instead of fiddling
bits, use a union of a SimpleValueType enum and a regular Type*.

This increases the size of MVT on 64-bit hosts from 32 bits to 64 bits.
In most cases, this doesn't add significant overhead. There are places
in codegen that use arrays of MVTs, so these are now larger, but
they're small in common cases.

This eliminates restrictions on the size of integer types and vector
types that can be represented in codegen. As the included testcase
demonstrates, it's now possible to codegen very large add operations.
There are still some complications with using very large types. PR2880
is still open so they can't be used as return values on normal targets,
there are no libcalls defined for very large integers so operations
like multiply and divide aren't supported.

This also introduces a minimal tablgen Type library, capable of
handling IntegerType and VectorType. This will allow parts of
TableGen that don't depend on using SimpleValueType values to handle
arbitrary integer and vector types.

add testcase for PR2964

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58393 91177308-0d34-0410-b5e6-96231b3b80d8

Add a RM pseudoreg for the rounding mode, which
allows ppcf128->int conversion to work with
DeadInstructionElimination.  This is now turned
off but RM is harmless.  It does not do a complete
job of modeling the rounding mode.

Revert marking MFCR as using all 7 CR subregisters;
while correct, this caused the problem in PR 2964,
plus the local RA crash noted in the comments.
This was needed to make DeadInstructionElimination,
but as we are not running that, it is backed out
for now.  Eventually it should go back in and the
other problems fixed where they're broken.

Add sanity checking for BUILD_PAIR (I noticed the
other day that PPC custom lowering could create
a BUILD_PAIR of two f64 with a result type of...
f64! - already fixed).  Fix a place that triggers
the sanity check.

Fix a FIXME: in ReplaceNodeWith, if the new node
is morphed by AnalyzeNewNode into a previously
processed node, and different result values of
that node are remapped to values with different
nodes, then we could end up using wrong values
here [we were assuming that all results remap
to values with the same underlying node].  This
seems theoretically possible, but I don't have
a testcase.  The meat of the patch is in the
changes to AnalyzeNewNode/AnalyzeNewValue and
ReplaceNodeWith.  While there, I changed names
like RemapNode to RemapValue, since it really
remaps values.  To tell the truth, I would be
much happier if we were only remapping nodes
(it would simplify a bunch of logic, and allow
for some cute speedups) but I haven't yet worked
out how to do that.
