Code has ended up depending on things like RSA's key generation being
deterministic given a fixed random Reader. This was never guaranteed and
would prevent us from ever changing anything about it.
This change makes certain calls randomly (based on the internal
fastrand) read an extra byte from the random Reader. This helps to
ensure that code does not depend on internal details.
I've not added this call in the key generation of ECDSA and DSA because,
in those cases, key generation is so obvious that it probably is
acceptable to do the obvious thing and not worry about code that depends
on that.
This does not affect tests that use a Reader of constant bytes (e.g. a
zeroReader) because shifting such a stream is a no-op. The stdlib uses
this internally (which is fine because it can be atomically updated if
the crypto libraries change).
It is possible that external tests could be doing the same and would
thus break if we ever, say, tweaked the way RSA key generation worked.
I feel that addressing that would be more effort than it's worth.

This function was added during the Go 1.11 dev cycle and isn't part of

In the previous implementation, NewGCMWithNonceAndTagSize was being used
as a helper function for NewGCM, NewGCMWithTagSize, and NewGCMWithNonceSize.
With the removal of Nonce size from the name and parameters, we needed to
add an unexported helper function newGCMWithNonceAndTagSize.

This line of the inlining tuning experiment
https://go-review.googlesource.com/c/go/+/109918/1/src/cmd/compile/internal/gc/inl.go#347
was incorrectly rewritten in a later patch to use the call
cost, not the panic cost, and thus the inlining of panic
didn't occur when it should. I discovered this when I
realized that tests should have failed, but didn't.
Fix is to make the correct change, and also to modify the
tests that this causes to fail. One test now asserts the
new normal, the other calls "ppanic" instead which is
designed to behave like panic but not be inlined.

CL 109340 added “minimal module-awareness for legacy operation.”
One part of that is reinterpreting imports inside code trees with go.mod files
as using semantic import versioning, and converting them back to
legacy import paths by stripping the major version element
(for example, interpreting import "x.com/foo/v2/bar" as import "x.com/foo/bar").
This rewrite was not being applied during "go get", with the effect that once
you had the target code downloaded already, everything was fine,
but it didn't download and build successfully the first time.
