Add instruction flags: hasExtraSrcRegAllocReq and hasExtraDefRegAllocReq. When
...
set, these flags indicate the instructions source / def operands have special
register allocation requirement that are not captured in their register classes.
Post-allocation passes (e.g. post-alloc scheduler) should not change their
allocations. e.g. ARM::LDRD require the two definitions to be allocated
even / odd register pair.

Improve MachineMemOperand handling.
...
- Allocate MachineMemOperands and MachineMemOperand lists in MachineFunctions.
This eliminates MachineInstr's std::list member and allows the data to be
created by isel and live for the remainder of codegen, avoiding a lot of
copying and unnecessary translation. This also shrinks MemSDNode.
- Delete MemOperandSDNode. Introduce MachineSDNode which has dedicated
fields for MachineMemOperands.
- Change MemSDNode to have a MachineMemOperand member instead of its own
fields with the same information. This introduces some redundancy, but
it's more consistent with what MachineInstr will eventually want.
- Ignore alignment when searching for redundant loads for CSE, but remember
the greatest alignment.
Target-specific code which previously used MemOperandSDNodes with generic
SDNodes now use MemIntrinsicSDNodes, with opcodes in a designated range
so that the SelectionDAG framework knows that MachineMemOperand information
is available.

reimplement the regex matching strategy by building a single
...
regex and matching it instead of trying to match chunks at a time.
Matching chunks at a time broke with check lines like
CHECK: foo {{.*}}bar
because the .* would eat the entire rest of the line and bar would
never match.
Now we just escape the fixed strings for the user, so that something
like:
CHECK: a() {{.*}}???
is matched as:
CHECK: {{a\(\) .*\?\?\?}}
transparently "under the covers".
