d8f05bf65e Reimplement (part of) the or -> add optimization. Matching 'or' into 'add' 
is general goodness because it allows ORs to be converted to LEA to avoid
inserting copies.  However, this is bad because it makes the generated .s
file less obvious and gives valgrind heartburn (tons of false positives in
bitfield code).

While the general fix should be in valgrind, we can at least try to avoid
emitting ADD instructions that *don't* get promoted to LEA.  This is more
work because it requires introducing pseudo instructions to represents
"add that knows the bits are disjoint", but hey, people really love valgrind.

This fixes this testcase:
https://bugs.kde.org/show_bug.cgi?id=242137#c20

the add r/i cases are coming next.

1d81101e97 After splitting, the remaining LiveInterval may be fragmented into multiple 
connected components. These components should be allocated different virtual
registers because there is no reason for them to be allocated together.

Add the ConnectedVNInfoEqClasses class to calculate the connected components,
and move values to new LiveIntervals.

Use it from SplitKit::rewrite by creating new virtual registers for the
components.

b8c38d92e4 Fix LSR to keep the RegUseTracker up to date when combining users. 
This doesn't usually matter, because the other heuristics usually
succeed regardless, but it's good to keep the register use
bookkeeping consistent.

16aa36001d convert test to use the existing classes that the multipatterns 
use.  Since TEST is completely different than all other binops,
don't define a multipattern for it.

This completes factorization of binops.

d7f7dc04f5 convert adc/sbb to a multipattern. Because the adde/sube nodes 
are not defined as returning EFLAGS (like add_flag and friends),
the entire multipattern and several of the subclasses need to be
cloned.

This could be handled through better instantiation support in tblgen,
but it isn't meta enough.
