Now the two OP formats are used for SDT marker argument in Arm64 ELF, one format is general register xNUM (e.g. x1, x2, etc), another is for using stack pointer to access local variables (e.g. [sp], [sp, 8]). This patch adds support SDT marker argument for Arm64, it parses OP and converts to uprobe compatible format.
