399dcc75a8 cmd/gc: fix &^ code generation bug
Was not re-walking the new AND node, so that its ullman
count was wrong, so that the code generator attempted to
store values in registers across the call.

Fixes #4752.

ffc742b658 cmd/gc: allow new conversion syntax
For consistency with conversions that look like function calls,
conversions that don't look like function calls now allow an
optional trailing comma.

That is, int(x,) has always been syntactically valid.
Now []int(x,) is valid too.

Fixes #4162.

does not handle padding at the end of a struct.

Handling of padding at end of structs also fixes the case

dc75670ae2 test: limit runoutput tests on arm platforms
runoutput styles tests generally consume a lot of memory. On arm platforms rotate?.go consume around 200mb each to compile, and as tests are sorted alphabetically, they all tend to run at once.

This change limits the number of runoutput jobs to 2 on arm platforms.

8fff2525cb cmd/gc: add space to export data to match linker expectations
The linker split PKGDEF into (prefix, name, def) pairs,
and defines def to begin after a space following the identifier.
This is totally wrong for the following export data:

        func "".FunctionName()
        var SomethingCompletelyUnrelated int

The linker would parse
    name=`"".FunctionName()\n\tvar`
    def=`SomethingCompletelyUnrelated int`
since there is no space after FunctionName.

9aef20e823 cmd/gc: fix wrong interaction between inlining and embedded builtins.
The patch makes the compile user an ordinary package-local
symbol for the name of embedded fields of builtin type.

This is incompatible with the fix delivered for issue 2687
(revision 3c060add43fb) but fixes it in a different way, because
the explicit symbol on the field makes the typechecker able to
find it in lookdot.

Fixes #3552.
