Use target_read_code in skip_prologue (amd64) 

gdb:

2013-12-10  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.
