Pierre-Marie de Rodat 6592d14b43 Add a flag to control the balance between GNAT encodings and std. DWARF
In order to accomodate the debugger's support evolution for "new" DWARF
constructs, we need to have an flag that controls the amount of GNAT
encodings/standard DWARF information that is emitted in the debug info.
Propagate this new parameter into the Ada front-end.

gcc/ChangeLog:

	* common.opt (gnat_encodings): New variable
	(dwarf_gnat_encodings): New enum type.
	(fgnat_encodings): New option.
	* flag-types.h (enum dwarf_gnat_encodings): New.

gcc/ada/ChangeLog:

	* gcc-interface/misc.c (gnat_encodings): Undefine macro and
	declare a global variable.
	(gnat_post_options): Initialize this global from options.

Segher Boessenkool 59faab7cc4 bb-reorder: Add -freorder-blocks-algorithm= and wire it up
This adds an -freorder-blocks-algorithm=[simple|stc] flag, with "simple"
as default.  For -O2 and up (except -Os) it is switched to "stc" instead.
Targets that never want STC can override this.  This changes -freorder-blocks
to be on at -O1 and up (was -O2 and up).

In effect, the changes are for -O1 (which now gets "simple" instead of
nothing), -Os (which now gets "simple" instead of "stc", since STC results
in much bigger code), and for targets that wish to never use STC (not in
this patch though).

Commit the vtable verification feature.  This feature is designed to
detect, at run time, if/when the vtable pointer in a C++ object has
been corrupted, before allowing virtual calls through that pointer. 
If pointer corruption is detected, execution of the program is halted.
