Make the check for global variables the same as the one for functions. In
...
both cases they are looking for non-external variables/functions that do
not have internal linkage. Using "!isExternal()" is a little more
understandable than "hasInitializer()"

Make sure to clear the LazyFunctionLoadMap after we ParseAllFunctionBodies.
...
Otherwise, clients who call ParseAllFunctionBodies will attempt to parse
the function bodies twice, which is (uh) very very bad (tm).
This fixes gccld on python.

Do not put internal symbols into the symbol table. This shrinks the symbol
...
table for archives in common cases, and prevents trying to resolve a
external reference with an internal reference. This shrinks the libpython.a
symbol table from 126302 to 19770 bytes.

Eliminate this ugly hack. This was put back in when replaceAllUsesOf used
...
a different algorithm that was extremely inefficient for instructions with
many operands.
This reduces the time of this code snippet from .23s for 176.gcc to 0.03s
in a debug build, which speeds up total llvm-dis time just barely.
It's more of a code cleanup than a speedup.

Correct the computation of when to add the padding. It is not based on the

length of a member's name.

* make sure we provide the full member name when searching for symbols so
the module name is not accidentally duplicated.
