This enables efficient use of the builtin min/max function
for float64 and float32 types on GOPPC64 >= power9.
Extend the assembler to support xsminjdp/xsmaxjdp and use
them to implement float min/max.
Simplify the VSX xx3 opcode rules to allow FPR arguments,
if all arguments are an FPR.

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 test cmd/internal/testdir
To run just tests from specified files in this directory, execute:
../bin/go test cmd/internal/testdir -run='Test/(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.
