Use the newly added SYM_FUNC_START_LOCAL to annotate starts of all
functions which do not have ".globl" annotation. This is needed to
balance SYM_FUNC_END for tools that are about to generate debuginfo.
Note that some functions already had ENDPROC -- switch to the new
SYM_FUNC_END too.
[v3] annotate more functions
