Map variable was not covered and faulty optimization could occur.
Ex.
t() ->
M0 = id(#{ "a" => 1 }),
#{ "a" := _ } = M0,
M0#{ "a" := b }.
M0 was lost in let expression optimization.

This fixes an error on multiple updates optimization for map pairs.
The error was introduced with moving to term order in Maps.
This also fixes an error where register life time was lost for values
and could result in erroneuos values being emitted in for map pairs.
Simplified v3_codegen by moving multiple update optimizations to v3_kernel.

We must not do the delayed binary creation optimization if the
code attempts to call the matched out binary. Calling a matchstate
will crash the run-time system.

Daniel Goertzen reported that commit 8a147a7365 broke building
of Erlang/OTP on Gentoo Linux because the macro OF() was missing.
Apparently, on Gentoo the OF() macro in zconf.h has been renamed
to _Z_OF() (to avoid polluting the global namespace).
Don't use the OF() macro in gzio.c since it no longer serves any
useful purpose (it provided compatibility with pre-ANSI/ISO C
compilers, but the rest of Erlang/OTP requires an ANSI/ISO C
compiler anyway).

In e12b7d5331c58b41db06cadfa4af75b78b62a2b1, a bug was introduced
that would cause case expressions to be evaluated more than once
if there were aliases in the pattern. Example:
X = Y = io:put_chars("some chars"),
{X,Y}
That would be rewritten to code similar to (but in Core Erlang):
X = io:put_chars("some chars"),
X = io:put_chars("some chars"),
{X,Y}
Make sure that we only evalute the expression once by doing a
transformation similar to (but in Core Erlang):
NewVar = io:put_chars("some chars"),
X = NewVar,
Y = NewVar,
{X,Y}

A test is commented-out in map_SUITE:t_update_exact/1, waiting for a fixed
maps:update/3 function with correct integer/float semantics.
