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.

There are two issues in the arm64 assembler.
1. "CMPW $0x22220000, RSP" is encoded to 5b44a4d2ff031b6b, which
is the combination of "MOVD $0x22220000, Rtmp" and
"NEGSW Rtmp, ZR".
The right encoding should be a combination of
"MOVD $0x22220000, Rtmp" and "CMPW Rtmp, RSP".
2. "AND $0x22220000, R2, RSP" is encoded to 5b44a4d25f601b00,
which is the combination of "MOVD $0x22220000, Rtmp" and
an illegal instruction.
The right behavior should be an error report of
"illegal combination", since "AND Rtmp, RSP, RSP" is invalid
in armv8.

The existing cycle detection scheme passes around a (type name)
path; when a type name re-appears in the path, a cycle is reported.
Indirections (as in *T, func(T), etc.) are broken by starting a new
(nil) path. The problem with this approach is that it doesn't work
for cycles involving alias type names since they may be invalid
even if there is an indirection. Furthermore, the path must be
passed around through all functions which is currently not the
case, which leads to less optimial error reporting.
The new code is using the previously introduced color marking
scheme and global object path for package-level cycle detection
(function-local cycle detection doesn't use the same code path
yet but is also much less important as cycles can only be created
using the type being declared).
The new code is guarded with an internal flag (useCycleMarking)
so it can be disabled in short notice if this change introduced
unexpected new issues.

The existing code explicitly passes a (type name) path around
to determine cycles; it also restarts the path for types that
"break" a cycle (such as a pointer, function, etc.). This does
not work for alias types (whose cycles are broken in a different
way). Furthermore, because the path is not passed through all
type checker functions that need it, we can't see the path or
use it for detection of some cycles (e.g. cycles involving array
lengths), which required ad-hoc solutions in those cases.
This change introduces an explicit marking scheme for any kind
of object; an object is painted in various colors indicating
its state. It also introduces an object path (a stack) main-
tained with the Checker state, which is available in all type
checker functions that need access to it.
The change only introduces these mechanisms and exercises the
basic functionality, with no effect on the existing code for
now.
