Currently, when copying definition node of an inlined var, we do not
update var Defn field to point to new copied node. That causes all
inlined vars point to the same Defn, and ir.StaticValue can not find
inlined var in the lhs of its definition.
clovar creates new ONAME node for local variables or params of closure
inside inlined function, by copying most of the old node fields. So the
new Node.Defn is not modified, its lhs still refer to old node
instead of new one.
To fix this, we need to do two things:
- In subst.clovar, set a dummy Defn node for inlvar
- During subst.node, when seeing OAS/OAS2 nodes, after substituting, we
check if any node in lhs has the dummy Defn, then set it to the current
OAS/OAS2 node.
Fixes#45606

The test directory contains tests of the Go tool chain and runtime.
It includes black box tests, regression tests, and error output tests.
They are run as part of all.bash.
To run just these tests, execute:
../bin/go run run.go
To run just tests from specified files in this directory, execute:
../bin/go run run.go -- file1.go file2.go ...
Standard library tests should be written as regular Go tests in the appropriate package.
The tool chain and runtime also have regular Go tests in their packages.
The main reasons to add a new test to this directory are:
it is most naturally expressed using the test runner; or
it is also applicable to gccgo and other Go tool chains.
