This benchmark is odd currently because it uses inconsistent cases
between benchmark iterations, and each iteration actually does a bit of
testing.
This separates the two benchmark cases into two separate benchmarks and
removes the testing done on each iteration. The unit tests above
suffice.
The benchmark being more succinct will make it easier to gauge the
benefits of any future MIME header reading changes.

Ending a loop with a break is confusing. Rewrite the loop so the

The existing code uses a type map which associates a type number
with a type; references to existing types are expressed via the
type number in the export data.
Before this CL, type map entries were set when a type was read
in completely, which meant that recursive references to types
(i.e., type map entries) that were in the middle of construction
(i.e., where the type map was not yet updated) would lead to nil
types. Such cycles are usually created via defined types which
introduce a types.Named entry into the type map before the underlying
type is parsed; in this case the code worked. In case of type aliases,
no such "forwarder" exists and type cycles lead to nil types.
This CL fixes the problem by a) updating the type map as soon as
a type becomes available but before the type's components are parsed;
b) keeping track of a list of type map entries that may need to be
updated together (because of aliases that may all refer to the same
type); and c) adding (redundant) markers to the type map to detect
algorithmic errors.
Also:
- distinguish between parseInt and parseInt64
- added more test cases
