correctness; it helps with compile time, as it avoids the need
for data- and anti-dependencies from all spills and reloads on
the stack-pointer modification.

scheduling, and generalize is so that preserves state across
scheduling regions. This fixes incorrect live-range information around
terminators and labels, which are effective region boundaries.

In place of looking for terminators to anchor inter-block dependencies,
introduce special entry and exit scheduling units for this purpose.

PTH: Replace ad hoc 'file name' -> 'PTH data' lookup table in the PTH file with an on-disk chained hash table.  This data structure is implemented using templates, and will be used to replace similar data structures.  This change leads to no visibile performance impact on Cocoa.h, but now we only pay a price for the table on order with the number of files accessed and not the number in the PTH file.

  We print out structure contents more often.
  We handle pass indentation information into the statement printer, so that

Function temporaries can not overlap with retval or args.See the comment in source code to know the reason. Anything having .auto. in its name is local to a function in nature irrespective of the linkage specified. print static local variables in module level IDATA section.

Function parameters for PIC16 are like local variables. So use the keyword ".auto." to mangle their names. The working of PIC16AsmPrinter relies on that keyword currently.
