something that just glues two nodes together, even if it is
sometimes used for flags.

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.

instead of srcvalue/offset pairs.  This corrects SV info for mem 
operations whose size is > 32-bits.

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

This should fix alot of problems we saw so far, e.g. PRs 5851 & 2936

as it emits code.  Switch .globl directives to use OutStreamer instead of
doing it textually (in x86)

Note that the code wasn't calling DecorateCygMingName
when emitting the ".ascii -export" stuff at the end of
file for DLLExported functions.  I don't know if it should
or not, but I'm preserving behavior.

Make dllexport directives come out in determinstic order.
