27107f6ab4 Some random comment, naming, and format changes. 
Rename the AttributeImpl* from Attrs to pImpl to be consistent with other code.
Add comments where none were before. Or doxygen-ify other comments.

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.

4766ef41b3 Aligned bundling support. Following the discussion here: 
http://lists.cs.uiuc.edu/pipermail/llvmdev/2012-December/056754.html

The proposal and implementation are fully documented here:
https://sites.google.com/a/chromium.org/dev/nativeclient/pnacl/aligned-bundling-support-in-llvm

Tests will follow shortly.

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 
physical register $r1 to $r0.

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