*	Track the locations of local variables using EF_debug annotations.	Xavier Leroy	2015-08-23	1	-8/+20
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	SimplLocals: - record locations of stack-allocated variables with annotations (of kind 5) at the beginning of the function; - mark every assignment to non-stack-allocated variables with an annotation of kind 2. Debugvar: (new pass!) - perform availability analysis for debug annotations of kind 2 - insert "start of live range" and "end of live range" annotations (kind 3 and 4) to delimit intervals of PCs where the location of a local variable is known.
*	Renaming {BA,BR}_longofwords -> {BA,BR}_splitlong.	Xavier Leroy	2015-08-22	1	-13/+18
\| \| \| \| \| \| \| \|	Use EF_debug instead of EF_annot for line number annotations. Introduce PrintAsmaux.print_debug_info (very incomplete). powerpc/Asmexpand: revise expand_memcpy_small.

*	Refactoring of builtins and annotations in the back-end.	Xavier Leroy	2015-08-21	1	-11/+11
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Before, the back-end languages had distinct instructions - Iannot for annotations, taking structured expressions (annot_arg) as arguments, and producing no results' - Ibuiltin for other builtins, using simple pseudoregs/locations/registers as arguments and results. This branch enriches Ibuiltin instructions so that they take structured expressions (builtin_arg and builtin_res) as arguments and results. This way, - Annotations fit the general pattern of builtin functions, so Iannot instructions are removed. - EF_vload_global and EF_vstore_global become useless, as the same optimization can be achieved by EF_vload/vstore taking a structured argument of the "address of global" kind. - Better code can be generated for builtin_memcpy between stack locations, or volatile accesses to stack locations. Finally, this commit also introduces a new kind of external function, EF_debug, which is like EF_annot but produces no observable events. It will be used later to transport debug info through the back-end, without preventing optimizations.
