8b7d7ade85 Add parameter to pattern classes to enable an itinerary to be specified for instructions. For now just use the existing itineraries or NoItinerary.

24f654c8a4 Fix several fixmes and clean up code by sinking *all* section 
creation activity into the target-specific subclasses of TLOF.
Before this, globals with explicit sections could be created by
the base class.

1. make getOrCreateSection protected, add a new getExplicitSectionGlobal
   pure virtual method to assign sections to globals with a specified
   section.
2. eliminate getSpecialCasedSectionGlobals, which is now PIC specific.
3. eliminate the getKindForNamedSection virtual method, which is
   now just a static method for ELF.
4. Add implementions of getExplicitSectionGlobal for ELF/PECOFF/Darwin/PIC16.
   They are now all detangled and understandable, woo! :)

a node identical to an existing node.

70cd88fb7b Add a new pre-allocation pass to assign adjacent registers for Neon instructions 
that have that constraint.  This is currently just assigning a fixed set of
registers, and it only handles VLDn for n=2,3,4 with DPR registers.
I'm going to expand it to handle more operations next; we can make it smarter
once everything is working correctly.

197f728d49 Fix FindExecutable to use sys::Path::GetMainExecutable instead of 
just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.

Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.
