This code used to be necessary because of the error messages generated
by the YACC-based parser, but they're no longer relevant under the new
recursive descent parser:
- LBRACE no longer exists, so "{ or {" can never occur.
- The parser never generates error messages about "@" or "?" now
(except in import sections, where they're actually legitimate).
- The s/LLITERAL/litbuf/ substitution is handled in p.syntax_error.

This adapts pem.TestFuzz to sanitize the generated Block fields,
because the encoder and wireformat do not differentiate between nil
and empty slices and maps, while reflect.DeepEqual rightfully does.
In the commit mentioned below, we adapt quick.Value in
testing/quick to generate these value states, which had heretofore
been impossible with the standard library fuzz test facility.
This commit is a piecemeal extraction from ...

The orders of the curves in crypto/elliptic are all very close to a
power of two. None the less, there is a tiny bias in the private key
selection.
This change makes the distribution uniform by resampling in the case
that a private key is >= to the order of the curve. (It also switches
from using BitSize to Params().N.BitLen() because, although they're the
same value here, the latter is technically the correct thing to do.)
The private key sampling and nonce sampling in crypto/ecdsa don't have
this issue.

The documentation was inconsistent. It said zero values were not sent, but
that zero-valued elements of arrays and arrays were sent. But which rule
applies if the array is all zero elements, and is therefore itself a zero value?
The answer is: the array is transmitted. In principle the other choice could
be made, but there would be considerable expense and complexity required
to implement this behavior now, not to mention worries about changes of
behavior.
Therefore we just document the situation: Arrays, slices, and maps are
always encoded. It would perhaps be nice to have sorted this out earlier,
but it was a missed opportunity.

If reports like #13062 are really concurrent misuse of maps,
we can detect that, at least some of the time, with a cheap check.
There is an extra pair of memory writes for writing to a map,
but to the same cache line as h.count, which is often being modified anyway,
and there is an extra memory read for reading from a map,
but to the same cache line as h.count, which is always being read anyway.
So the check should be basically invisible and may help reduce the
number of "mysterious runtime crash due to map misuse" reports.

It is because the corresponding symbol (Sym field in Type object)

Just skip the symbol if it is nil, so that the error message becomes:
