gdbarch: add instruction predicate methods

Browse Source 
Add new methods to gdbarch for analyzing the instruction at a given address.
Implement those methods for i386 and amd64 architectures.

This is needed by "record btrace" to detect function calls in the
execution trace.

2014-01-16  Markus Metzger  <markus.t.metzger@intel.com>

	* amd64-tdep.c (amd64_classify_insn_at, amd64_insn_is_call)
	(amd64_insn_is_ret, amd64_insn_is_jump, amd64_jmp_p): New.
	(amd64_init_abi): Add insn_is_call, insn_is_ret, and insn_is_jump
	to gdbarch.
	* i386-tdep.c (i386_insn_is_call, i386_insn_is_ret)
	(i386_insn_is_jump, i386_jmp_p): New.
	(i386_gdbarch_init): Add insn_is_call, insn_is_ret, and
	insn_is_jump to gdbarch.
	* gdbarch.sh (insn_is_call, insn_is_ret, insn_is_jump): New.
	* gdbarch.h: Regenerated.
	* gdbarch.c: Regenerated.
	* arch-utils.h (default_insn_is_call, default_insn_is_ret)
	(default_insn_is_jump): New.
	* arch-utils.c (default_insn_is_call, default_insn_is_ret)
	(default_insn_is_jump): New.
