target/i386: Add GDB XML description for SSE registers
Add an XML description for SSE registers (XMM+MXCSR) for both X86 and X86-64 architectures in the GDB stub: - configure: Define gdb_xml_files for the X86 targets (32 and 64bit). - gdb-xml/i386-32bit-sse.xml & gdb-xml/i386-64bit-sse.xml: The XML files that contain a description of the XMM + MXCSR registers. - gdb-xml/i386-32bit.xml & gdb-xml/i386-64bit.xml: wrappers that include the XML file of the core registers and the other XML file of the SSE registers. - target/i386/cpu.c: Modify the gdb_core_xml_file to the new XML wrapper, modify the gdb_num_core_regs to fit the registers number defined in each XML file.
