The address space starts at 4GB, so dummy is too far out.
This CL is part of a stack adding windows/arm64
support (#36439), intended to land in the Go 1.17 cycle.

Unlike iOS, macOS ARM64 is more of a fully featured OS. Enable

This commit adapts compile tool to create correct nilchecks for AIX.
AIX allows to load a nil pointer. Therefore, the default nilcheck
which issues a load must be replaced by a CMP instruction followed by a
store at 0x0 if the value is nil. The store will trigger a SIGSEGV as on
others OS.
The nilcheck algorithm must be adapted to do not remove nilcheck if it's
only a read. Stores are detected with v.Type.IsMemory().
Tests related to nilptr must be adapted to the previous changements.
nilptr.go cannot be used as it's because the AIX address space starts at
1<<32.

These tests were suggested in golang.org/issue/6080.
They were fixed as part of the new nil pointer checks
that I added a few weeks ago.
Recording the tests as part of marking the issue closed.
Fixes#6080.

The 512 MB array causes load delays on some systems.
Now that we have recover, we can do all the tests in
one binary, so that the delay is incurred just once.
