[PATCH 2/3] skip_prolgoue (amd64)

[Yao Qi <yao@codesourcery.com>]

gdb:

2013-11-29  Yao Qi  <yao@codesourcery.com>

	* amd64-tdep.c (amd64_analyze_stack_align): Call
	target_read_code instead of target_read_memory.
	(amd64_analyze_prologue): Call read_code_unsigned_integer
	instead of read_memory_unsigned_integer.  Call read_code
	instead of read_memory.
	(amd64_skip_xmm_prologue): Likewise.
