#5745 [Code Reorganization] code cleanup and code style fix
This is a huge patch, but only code cleanup, code style fix and useless code deletion are included, for example:
tab -> two spaces, deleted spacees at the end of a line, delete useless comments.
This patch also included:
Declaration and definition of class MacroAssembler is moved from assembler_mips.h/cpp to macroAssembler_mips.h/cpp
