instead of requiring all "short description" strings to begin with
two spaces. This makes these strings less mysterious, and it fixes
some cases where short description strings mistakenly did not
begin with two spaces.

 - Follows the MSVC (original) implementation, including support of
   pack(show) (useful for testing).
 - Implements support for named pack records which gcc seems to
   ignore (or implements incorrectly).
 - Not currently wired to anything, only functionality change is the
   type checking of the pragma.

create a new DAG node to represent the new shift to keep the
DAG consistent, even though it'll almost always be folded into
the address.

If a user of the resulting address has multiple uses, the
nodes may get revisited by a later MatchAddress call, in which
case DAG inconsistencies do matter.

This fixes PR2849.

passes without -m64 on x86-32-linux, just remove
the -m64.
