rememberInstruction so that future users of that user will be inserted
in the correct position. This fixes the Darwin selfhost.

if one of the vectors didn't have elements (such as undef). Fixes PR 6096.

Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would
have <2 x i1> type if constant folding was successful and i1 type if it wasn't.
This exposed a related issue in the bitcode reader.

This new version is much more aggressive about doing "full" reduction in
cases where it reduces register pressure, and also more aggressive about
rewriting induction variables to count down (or up) to zero when doing so
reduces register pressure.

It currently uses fairly simplistic algorithms for finding reuse
opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.

Fix a minor issue in x86 load / store folding table. movups does an unaligned load so it doesn't require 16-byte alignment.

rather than passing them off to the AsmLexer to handle.
This means the AsmLexer no longer requires a SourceMgr
to do error handling.

this makes function stub emission determinstic.

MachineModuleInfoMachO instead.  This eliminates two sources
of nondeterministic output in the ppc backend, but function
stubs are still bad.

When XDEBUG is enabled, check for SelectionDAG cycles at some key
points.  This will help us find future problems like the one
described in PR6019.
