rename MVT::Flag to MVT::Glue. "Flag" is a terrible name for
...
something that just glues two nodes together, even if it is
sometimes used for flags.

When passing a huge parameter using the byval mechanism, a long
...
sequence of loads and stores was being generated to perform the
copy on the x86 targets if the parameter was less than 4 byte
aligned, causing llc to use up vast amounts of memory and time.
Use a "rep movs" form instead. PR7170.

reimplement memcpy/memmove/memset lowering to use MachinePointerInfo

Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.
