I verified this change on a corpus of > 200 GB of emails since the mid-90s. With
this change, more addresses parse than before, and anything which parsed before
still parses.
In said corpus, I came across the edge case of comments preceding an
addr-spec (with angle brackets!), e.g. “(John Doe) <john@example.com>”, which
does not satisfy the conditions to be treated as a fallback, as per my reading
of RFC2822.
This change does not parse quoted-strings within comments (a corresponding TODO
is in the code), but I have not seen that in the wild.

CL 45412 started hiding autogenerated wrapper functions from call
stacks so that call stack semantics better matched language semantics.
This is based on the theory that the wrapper function will call the
"real" function and all the programmer knows about is the real
function.
However, this theory breaks down in two cases:
1. If the wrapper is at the top of the stack, then it didn't call
anything. This can happen, for example, if the "stack" was actually
synthesized by the user.
2. If the wrapper panics, for example by calling panicwrap or by
dereferencing a nil pointer, then it didn't call the wrapped
function and the user needs to see what panicked, even if we can't
attribute it nicely.
This commit modifies the traceback logic to include the wrapper
function in both of these cases.

with go:noescape, telling the compiler that we know pointers do not
escape from it.
By annotating the assembly functions in the s390x P256 code in this way
we enable more variables to be allocated on the stack rather than

cmd/cover rewrites Go source code to add coverage annotations.
The approach to date has been to parse the code to AST, analyze it,
rewrite the AST, and print it back out. This approach fails to preserve
line numbers in the original code and has a very difficult time with
comments, because go/printer does as well.
This CL changes cmd/cover to decide what to modify based on the
AST but to apply the modifications as purely textual substitutions.
In this way, cmd/cover can be sure it never adds or removes a newline
character, nor a comment, so all line numbers and comments are
preserved.
This also allows us to emit a single //line comment at the beginning
of the translated file and have the compiler report errors with
correct line numbers in the original file.
