Keith Randall d949d0b925 cmd/compile: reorganize init functions
Instead of writing an init function per package that does the same
thing for every package, just write that implementation once in the
runtime. Change the compiler to generate a data structure that encodes
the required initialization operations.

Reduces cmd/go binary size by 0.3%+.  Most of the init code is gone,
including all the corresponding stack map info. The .inittask
structures that replace them are quite a bit smaller.

Most usefully to me, there is no longer an init function in every -S output.
(There is an .inittask global there, but it's much less distracting.)

After this CL we could change the name of the "init.ializers" function
back to just "init".

Update #6853

R=go1.13

Robert Griesemer cf710949a9 Revert "cmd/compile: improve error message if init is directly invoked"
This reverts commit cb6e0639fb.

The fix is incorrect as it's perfectly fine to refer to an
identifier 'init' inside a function, and 'init' may even be
a variable of function value. Misspelling 'init' in that
context would lead to an incorrect error message.

Reopened #8481.

Emmanuel Odeke cb6e0639fb cmd/compile: improve error message if init is directly invoked
Fixes #8481.

Inform the user that init functions cannot be directly invoked
in user code, as mandated by the spec at:

Gustavo Niemeyer daffc2d2ef gc: fix init of packages named main
This change removes the special case which existed
for handling the initalization of the main package,
so that other modules named 'main' get properly
initialized when imported.

Note that gotest of main packages will break in most
cases without this.
