103b4a571e Revert "Adding support for llvm.arm.neon.vaddl[su].* and"
This reverts r170694.  The operations can be represented in IR without
adding any new intrinsics.

8386acd734 LoopVectorize: Fix a bug in the scalarization of instructions.
Before if-conversion we could check if a value is loop invariant
if it was declared inside the basic block. Now that loops have
multiple blocks this check is incorrect.

This fixes External/SPEC/CINT95/099_go/099_go

139e407d52 On some ARM cpus, flags setting movs with shifter operand, i.e. lsl, lsr, asr,
are more expensive than the non-flag setting variant. Teach thumb2 size
reduction pass to avoid generating them unless we are optimizing for size.

b17201f1b8 Add a largish auto-generated test for the aligned bundling feature, along with
the script generating it. The test should never be modified manually. If anyone
needs to change it, please change the script and re-run it.

The script is placed into utils/testgen - I couldn't think of a better place,
and after some discussion on IRC this looked like a logical location.

7f6ece8a93 Use MachineInstrBuilder in InstrEmitter.
This is supposed to be a mechanical change with no functional effects.

InstrEmitter can generate all types of MachineOperands which revealed
that MachineInstrBuilder was missing a few methods, added by this patch.

Besides providing a context pointer to MI::addOperand(),
MachineInstrBuilder seems like a better fit for this code.

67ae135759 Add a new attribute, 'noduplicate'. If a function contains a noduplicate call, the call cannot be duplicated - Jump threading, loop unrolling, loop unswitching, and loop rotation are inhibited if they would duplicate the call.
Similarly inlining of the function is inhibited, if that would duplicate the call (in particular inlining is still allowed when there is only one callsite and the function has internal linkage).

68fe665b9a [mips] Use "or $r0, $r1, $zero" instead of "addu $r0, $zero, $r1" to copy

GNU disassembler recognizes an "or" instruction as a "move", and this change
makes the disassembled code easier to read.

6241703ee4 docs: Clean up adornments.
For whatever reason the usage of '^^^' and '---' adornments were
reversed compared to the "canonical" style of the LLVM docs (which is
currently "the style used in SphinxQuickstartTemplate.rst"). This change
doesn't affect the document structure at all, I'm just doing it for
trivial stylistic consistency (the document content is *much* more
important---thanks Nadav for writing this up!).

Also, trim the adornments to be the same length as the section names.
