Daniel Martí 14d3803a7b fix hashing of generic field names
Trying to make Go master work, I noticed that crypto/tls still failed to
build. The reason was generic structs; we would badly obfuscate their
field names when the types are instantiated:

	> garble build
	[stderr]
	# test/main
	Z4ZpcbMj.go:4: unknown field 'FOpszkrN' in struct literal of type SYdpWfK5[string]
	Z4ZpcbMj.go:5: m8hLTotb.FypXrbTd undefined (type SYdpWfK5[string] has no field or method FypXrbTd)
	exit status 2

See the added comment for what happened and how we fixed it. And add tests.

Daniel Martí 61bd95bb89 add a test with generic code
This ensures that we support obfuscating builds containing the use of
type parameters, the new feature in Go 1.18.
The test is small for now, but we can extend it over time.

There was just one bug that kept the code from obfuscating properly;
that has been fixed in https://go.dev/cl/405194,
and we update x/tools to the latest master version to include it.

Fixes #414.
