Keith Randall 0ad332d80c cmd/compile: implement some moves using non-overlapping reads&writes

For moves >8,<16 bytes, do a move using non-overlapping loads/stores
if it would require no more instructions.

This helps a bit with the case when the move is from a static
constant, because then the code to materialize the value being moved
is smaller.

README.md

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

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.
