qmuntal 176a2154aa cmd/link: use >4GB base address for 64-bit PE binaries

Windows prefers 64-bit binaries to be loaded at an address above 4GB.

Having a preferred base address below this boundary triggers a
compatibility mode in Address Space Layout Randomization (ASLR) on
recent versions of Windows that reduces the number of locations to which
ASLR may relocate the binary.

The Go internal linker was using a smaller base address due to an issue
with how dynamic cgo symbols were relocated, which has been fixed in
this CL.

Fixes #73561.

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.
