5c2666c18c gc: unsafe.Pointer is not a pointer
Change unsafe.Pointer to be its own kind of
type, instead of making it equivalent to *any.
The change complicates import and export
but avoids the need to find all the places that
operate on pointers but should not operate on
unsafe.Pointer.

Fixes #1566. (a different way)
Fixes #1582.

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.

5b1b2ba9c7 runtime: new allocation strategy for amd64
Do not reserve virtual address space.
Instead, assume it will be there when we need it,
and crash loudly if that assumption is violated.
Reserving the address space gets charged to
ulimit -v, which exceeds commonly set limits.

(https://golang.org/cl/2609041) and neglected
to look at 5l and 8l to see if they were affected.

On the positive side, the check I added in that CL is the
one that detected this bug.

4608feb18b runtime: simpler heap map, memory allocation
The old heap maps used a multilevel table, but that
was overkill: there are only 1M entries on a 32-bit
machine and we can arrange to use a dense address
range on a 64-bit machine.

The heap map is in bss.  The assumption is that if
we don't touch the pages they won't be mapped in.

Also moved some duplicated memory allocation
code out of the OS-specific files.
