cmd/compile: remove -wrapglobalmapinit flag

Browse source 
Remove the compiler's "-wrapglobalmapinit" flag; it is potentially
confusing for users and isn't appropriate as a top level flag. Move
the enable/disable control to the "wrapglobalmapctl" debug flag
(values: 0 on by default, 1 disabled, 2 stress mode). No other changes
to compiler functionality.
