URLs in GOPROXY may now be separated with commas (,) or pipes (|). If
a request to a proxy fails with any error (including connection errors
and timeouts) and the proxy URL is followed by a pipe, the go command
will try the request with the next proxy in the list. If the proxy is
followed by a comma, the go command will only try the next proxy if
the error a 404 or 410 HTTP response.
The go command will determine how to connect to the checksum database
using the same logic. Before accessing the checksum database, the go
command sends a request to <proxyURL>/sumdb/<sumdb-name>/supported.
If a proxy responds with 404 or 410, or if any other error occurs and
the proxy URL in GOPROXY is followed by a pipe, the go command will
try the request with the next proxy. If all proxies respond with 404
or 410 or are configured to fall back on errors, the go command will
connect to the checksum database directly.
This CL does not change the default value or meaning of GOPROXY.

If TestMain reports a wrong exit code to os.Exit, the test will be
exited with exist code inconsist with test results.
This CL eliminates the requirement of calling os.Exit in TestMain.
Now, m.Run records the execution status of its test, the outer
main func will call os.Exit with that exit code if TestMain does
not call os.Exit.
If TestMain does not call m.Run, the outer main func remain calls
os.Exit(0) as before.

Make panics more useful by printing values, if their
underlying kind is printable, instead of just their memory address.
Thus now given any custom type derived from any of:
float*, int*, string, uint*
if we have panic with such a result, its value will be printed.
Thus given any of:
type MyComplex128 complex128
type MyFloat64 float64
type MyString string
type MyUintptr uintptr
panic(MyComplex128(32.1 + 10i))
panic(MyFloat64(-93.7))
panic(MyString("This one"))
panic(MyUintptr(93))
They will now print in the panic:
panic: main.MyComplex64(+1.100000e-001+3.000000e+000i)
panic: main.MyFloat64(-9.370000e+001)
panic: main.MyString("This one")
panic: main.MyUintptr(93)
instead of:
panic: (main.MyComplex128) (0xe0100,0x138cc0)
panic: (main.MyFloat64) (0xe0100,0x138068)
panic: (main.MyString) (0x48aa00,0x4c0840)
panic: (main.MyUintptr) (0xe0100,0x137e58)
and anything else will be printed as in the past with:
panic: (main.MyStruct) (0xe4ee0,0x40a0e0)
Also while here, updated the Go1.15 release notes.

This removes much of the complexity of the implementation and use of
the cmd/go/internal/cmdflag package, and makes the behavior of GOFLAGS
in 'go test' and 'go vet' more consistent with other subcommands.
Some of the complexity reduction has been offset by code comments and
bug fixes, particularly for the handling of GOPATH arguments and flag
terminators ('--').
