Previous implementation has a check on pointer size but only if ptrSize
is 4. but it does not check on ptrSize 8 causing the panic on read for
some inputs.
The explicit check for pointer size 8 is added and error is returned if
ptrSize is not 4 and not 8.

When it calculates the smallest n such that:

the expression should be
(i+buildInfoAlign-1)&^(buildInfoAlign-1)
instead of
(i+buildInfoAlign-1)&^buildInfoAlign

Since a String method cannot return an error, escape fields that may
contain unsanitized values, and unescape them during parsing.
Add a fuzz test to verify that calling the String method on any
BuildInfo returned by Parse produces a string that parses to the same
BuildInfo. (Note that this doesn't ensure that String always produces
a parseable input: we assume that a user constructing a BuildInfo
provides valid paths and versions, so we don't bother to escape those.
It also doesn't ensure that ParseBuildInfo accepts all inputs that
ought to be valid.)

As a side effect of the changes in cmd/go/internal/work in CL 369977,
binaries built in GOPATH mode now include rudimentary build metadata
for at least the package path and compiler in use.
That seems like a strict improvement, but the test needs to be updated
to reflect the newly-available metadata.

Reading the version information to date has required evaluating
two pointers to strings (which themselves contain pointers to data),
which means applying relocations, which can be very system-dependent.
To simplify the lookup, inline the string data into the build info blob.
This makes go version work on binaries built with external linking
on darwin/arm64.
Also test that at least the very basics work on a trivial binary,
even in short mode.

Make Settings more closely align with command-line flags
and environment variables.
- Change command-line flags to begin with -
- Change syntax of build lines to use Key=Value instead of Key<tab>Value.
- Change CGO_ENABLED to 0/1, matching environment variable,
instead of false/true.
- Add GOOS and GOARCH.
These are technically redundant, in that they can be extracted
from the binary in other ways most of the time, but not always:
GOOS=ios and GOOS=darwin may produce binaries that are
difficult to tell apart. In any case, it's a lot easier to have them
directly in the settings list than derive them from other parts
of the binary.
- Add GOEXPERIMENT.
These could be inferred from the tags list, but the experiments
are being removed from the tags list.
- Change the tags list to match the -tags command-line argument.
- Add msan and race, echoing the -msan and -race arguments
(always 'true' when present, omitted when false).
- Add GO$GOARCH when set.

These functions provide access to module information stamped into Go
binaries. In the future, they'll provide access to other information
(like VCS info).
These functions are added in a new package instead of runtime/debug
since they use binary parsing packages like debug/elf, which would
make runtime/debug an unacceptably heavy dependency. The types in
runtime/debug are still used; debug/buildinfo uses them via type
aliases.
This information is already available for the running binary through
debug.ReadBuildInfo and for other binaries with 'go version -m', but
until now, there hasn't been a way to get it for other binaries
without installing cmd/go.
This change copies most of the code in cmd/go/internal/version. A
later CL will migrate 'go version -m' to use this package.
