I am not sure what are the consequences as gdb never printed any values for me.
But it looks unnecessary to manually duplicate it.

Technically a language change, this cleanup is a completely
backward compatible change that brings the boolean results
of comma-ok expressions in line with the boolean results of
comparisons: they are now all untyped booleans.

The implementation effort should be minimal (less than a
handfull lines of code, depending how well factored the
implementation of comma-ok expressions is).

Fixes #8189.

Several reasons:
1. Significantly simplifies runtime.
2. This code proved to be buggy.
3. Free is incompatible with bump-the-pointer allocation.
4. We want to write runtime in Go, Go does not have free.
5. Too much code to free env strings on startup.

Stand-alone this test is fine.  Run together with
others, however, the stack used can actually go
negative because other tests are freeing stack
during its execution.

This behavior is new with the new stack allocator.
The old allocator never returned (min-sized) stacks.

This test is fairly poor - it needs to run in
isolation to be accurate.  Maybe we should delete it.

The DISPATCH and CALLFN macro definitions depend on an inconsistency
between the internal cpp mini-implementation and the language proper in
whether center-dot is an identifier character. The macro depends on it not
being an identifier character, but the resulting code depends on it being one.

Remove the dependence on the inconsistency by placing the center-dot into
the macro invocation rather that the body.

No semantic change. This is just renaming macro arguments.

This change introduces gomallocgc, a Go clone of mallocgc.
Only a few uses have been moved over, so there are still
lots of uses from C. Many of these C uses will be moved
over to Go (e.g. in slice.goc), but probably not all.
What should remain of C's mallocgc is an open question.
