Joerg Sonnenberger cc9c8eb837 Bug#8945: Add -cxx-isystem option to specify C++ system directories. 
It works like -isystem and the search path keeps -isystem and
-cxx-isystem in order relative to each other. -cxx-isystem is only used
for C++ sources though. Drop the existing -cxx-system-include option for
cc1 as it is now redundant.

Richard Smith 59006e4338 Fix a few auto-related issues: 
* 'auto' was being rejected on abstract-declarators with trailing return
types and on typedefs with trailing return types. 'auto' is always
allowed in these cases. This was found while testing the fix for PR 9278.

 * A very poor diagnostic was being issued for auto (f() -> int): "return
type must be 'auto', not 'auto'". This is closely related to PR 9060.

 * Trailing return type handling was happening slightly too late,
resulting in the checks for functions returning arrays and functions
returning functions being missed.

Devang Patel f3292b2196 Revert r124611 - "Keep track of incoming argument's location while emitting LiveIns." 
In other words, do not keep track of argument's location.  The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body.
This requires some coordination with debugger to get this working. 
 - The debugger needs to be aware of prolog_end attribute attached with line table entries.
 - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+)

Richard Smith 27e39b11b1 C++0x's deduced auto is illegal in typedefs. 
This actually rules out too much, since it also catches typedefs for pointers to functions with trailing return types:

  typedef auto (*F)() -> int;

Fix for that (and the same issue in all abstract-declarators) to follow shortly.

Jakob Stoklund Olesen 60a26a6578 Add SplitKit::isOriginalEndpoint and use it to force live range splitting to terminate. 
An original endpoint is an instruction that killed or defined the original live
range before any live ranges were split.

When splitting global live ranges, avoid creating local live ranges without any
original endpoints. We may still create global live ranges without original
endpoints, but such a range won't be split again, and live range splitting still
terminates.
