Chris Lattner 0ab5e2cded Fix a ton of comment typos found by codespell. Patch by 
Luis Felipe Strano Moraes!

Chris Lattner 3e5fbd74ed 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.

Duncan Sands 98512315f7 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.

Chris Lattner 4470c2bb23 Fix a bug where the x86 backend would lower memcpy/memset of segment relative operations 
into non-segment-relative copies.

Chris Lattner 2510de2bea reimplement memcpy/memmove/memset lowering to use MachinePointerInfo 
instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

Dan Gohman bb919dfb6b Implement a bunch more TargetSelectionDAGInfo infrastructure. 
Move EmitTargetCodeForMemcpy, EmitTargetCodeForMemset, and
EmitTargetCodeForMemmove out of TargetLowering and into
SelectionDAGInfo to exercise this.

Dan Gohman 9becdddc49 Add skeleton target-specific SelectionDAGInfo files.
