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.
