Junyang Shao 558f5372fc cmd/compile,testing: implement one-time rampup logic for testing.B.Loop

testing.B.Loop now does its own loop scheduling without interaction with b.N.
b.N will be updated to the actual iterations b.Loop controls when b.Loop returns false.

This CL also added tests for fixed iteration count (benchtime=100x case).

This CL also ensured that b.Loop() is inlined.

For #61515

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 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.
