Dan Scales 225f484c88 misc, runtime, test: extra tests and benchmarks for defer 
Add a bunch of extra tests and benchmarks for defer, in preparation for new
low-cost (open-coded) implementation of defers (see #34481),

 - New file defer_test.go that tests a bunch more unusual defer scenarios,
   including things that might have problems for open-coded defers.
 - Additions to callers_test.go actually verifying what the stack trace looks like
   for various panic or panic-recover scenarios.
 - Additions to crash_test.go testing several more crash scenarios involving
   recursive panics.
 - New benchmark in runtime_test.go measuring speed of panic-recover
 - New CGo benchmark in cgo_test.go calling from Go to C back to Go that
   shows defer overhead

Updates #34481

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.
