The frontend may emit node with line number missing. In this case,
use the parent line number. Instead of changing every call site of
pushLine, do it in pushLine itself.
Fixes#16214.

Since CL 23620, TestAssembly is failing on Plan 9.
In CL 23620, the process environment is passed to 'go tool compile'
after setting GOARCH. On Plan 9, if GOARCH is already set in the
process environment, it would take precedence. On Unix, it works
as expected because the first GOARCH found takes precedence.
This change uses the mergeEnvLists function from cmd/go/main.go
to merge the two environment lists such that variables with the
same name in "in" replace those in "out".

In particular, this stops the test failing when GOROOT and GOROOT_FINAL are
different.

Add a test which compiles a function and checks the
generated assembly to make sure certain patterns are present.
This test allows us to do white box tests of the compiler
to make sure optimizations don't regress.
Added a few simple tests for now. More to come.
