c69bd733c0 RegioInfo: Add getExpandedRegion().
getExpandedRegion() enables us to create non canonical regions. Those regions
can be used to define the largerst region, that fullfills a certain property.

to add 10+ lines to every instruction.

2ab36d3502 Begin adding static dependence information to passes, which will allow us to
perform initialization without static constructors AND without explicit initialization
by the client.  For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve.  I hope to be able to relax
the latter requirement in the future.

d0eeeeb558 Remove the x86 MOV{32,64}{rr,rm,mr}_TC instructions.
The reg-reg copies were no longer being generated since copyPhysReg copies
physical registers only.

TAILJMP and TCRETURN instructions, there should be no need for constrained loads
and stores.

40ef4fe82a Properly handle reloading and spilling around partial redefines in
LocalRewriter.

This is a bit of a hack that adds an implicit use operand to model the
read-modify-write nature of a partial redef. Uses and defs are rewritten in
separate passes, and a single operand would never be processed twice.

7d24705f65 Change register allocation order for ARM VFP and NEON registers to put the
callee-saved registers at the end of the lists.  Also prefer to avoid using
the low registers that are in register subclasses required by certain
instructions, so that those registers will more likely be available when needed.
This change makes a huge improvement in spilling in some cases.  Thanks to
Jakob for helping me realize the problem.

Most of this patch is fixing the testsuite.  There are quite a few places
where we're checking for specific registers.  I changed those to wildcards
in places where that doesn't weaken the tests.  The spill-q.ll and
thumb2-spill-q.ll tests stopped spilling with this change, so I added a bunch
of live values to force spills on those tests.

a bit.

only end up emitting LEA instead of OR.  If we aren't able to promote
something into an LEA, we should never be emitting it as an ADD.

Add some testcases that we emit "or" in cases where we used to produce
an "add".

122e2ea043 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.

8a52fa674b Implement two virtual functions in SPUTargetLowering.
Before the implementation of isLegalAddressingMode, some rare cases 
of code were miscompiled if optimized with the LoopStrengthReduce pass.
It is unclear (to me) if LSR is "allowed" to produce wrong code with a 
bad TargetLowering, or if the bug is elsewhere and this patch just 
hides it.

defined exactly the same way instead of being close relatives.

4b181c87de Convert 'and' to single instance of a multipattern
which instantiates the 34 versions of and all in one
swoop.  The BaseOpc/BaseOpc2/BaseOpc4 stuff should not
be required, but tblgen's feeble brain explodes when I
use Or4<BaseOpc>.V in the multipattern.

No change in the generated .inc files.

511c686f76 add a new BinOpAI class to represent the immediate form that directly acts on EAX.
This does change the generated .inc files to include the implicit use/def of eax.
Since these instructions are only generated by the assembler and disassembler it
doesn't actually matter though.
