Bill Wendling aee679bf35 Modify the comparison optimizations in the peephole optimizer to update the 
iterator when an optimization took place. This allows us to do more insane
things with the code than just remove an instruction or two.

Dale Johannesen baa5d045c9 Add X86 MMX type to bitcode and Type. 
(The Ada bindings probably need it too, but all the
obvious places to change say "do not edit this file".)

reserved regs and that register allocators need to explicitly check for
them.

that the memoperands are properly set after DAG building and general mucking
about.

NAKAMURA Takumi 9c8a97ce0a Makefile.rules: LOADABLE_MODULE/Win32: "all" components may be linked

Bob Wilson 8617234658 Fix merging base-updates for VLDM/VSTM: Before I switched these instructions 
to use AddrMode4, there was a count of the registers stored in one of the
operands.  I changed that to just count the operands but forgot to adjust for
the size of D registers.  This was noticed by Evan as a performance problem
but it is a potential correctness bug as well, since it is possible that this
could merge a base update with a non-matching immediate.

Evan Cheng bf4070756f Teach if-converter to be more careful with predicating instructions that would 
take multiple cycles to decode.
For the current if-converter clients (actually only ARM), the instructions that
are predicated on false are not nops. They would still take machine cycles to
decode. Micro-coded instructions such as LDM / STM can potentially take multiple
cycles to decode. If-converter should take treat them as non-micro-coded
simple instructions.

Dan Gohman 6dbbab6895 Discard metadata produced by LLVM 2.7. The value enumeration it used 
is different from what the code now uses in a two ways: NamedMDNodes
were considered Values and included in the numbering, and the
function-local metadata counter wasn't reset between functions.

The later problem breaks lazy deserialization, so instead of trying
to emulate the old numbering, just drop the old metadata. The only
in-tree use case is debug info with LTO, where the QOI loss is
considered acceptable.

Daniel Dunbar e5444a88cd llvm-mc: Don't crash when using -n and we see a directive before the initial section. 
- This is annoying, because we have to scatter this check everywhere that could emit real data, but I see no better solution.

Owen Anderson 04cf3fd761 What the loop unroller cares about, rather than just not unrolling loops with calls, is 
not unrolling loops that contain calls that would be better off getting inlined.  This mostly
comes up when an interleaved devirtualization pass has devirtualized a call which the inliner
will inline on a future pass.  Thus, rather than blocking all loops containing calls, add
a metric for "inline candidate calls" and block loops containing those instead.

Owen Anderson 6270515918 Revert r113439, which relaxed the requirement that loops containing calls cannot be unrolled. After some discussion, 
there seems to be a better way to achieve the same effect.

Owen Anderson 62ea1b718c Use code-size reduction metrics to estimate the amount of savings we'll get when we unroll a loop. 
Next step is to recalculate the threshold values given this new heuristic.

Evan Cheng 367a5df8cf For each instruction itinerary class, specify the number of micro-ops each 
instruction in the class would be decoded to. Or zero if the number of
uOPs must be determined dynamically.

This will be used to determine the cost-effectiveness of predicating a
micro-coded instruction.
