a38c737e85 When a function takes a variable number of pointer arguments, with a zero 
pointer marking the end of the list, the zero *must* be cast to the pointer
type.  An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.

The new END_WITH_NULL macro may be used to annotate a such a function
so that GCC (version 4 or newer) will detect the use of un-casted zero
at compile time.

14db91a643 Use a map to cache the ModuleType information, so we can do logarithmic 
lookups instead of linear time lookups.  This speeds up bc parsing of a
large file from

137.834u 118.256s 4:27.96
to
132.611u 114.436s 4:08.53

with a release build.

4b688a1c70 This mega patch converts us from using Function::a{iterator|begin|end} to 
using Function::arg_{iterator|begin|end}.  Likewise Module::g* -> Module::global_*.

This patch is contributed by Gabor Greif, thanks!

a7a01f13df 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()"

1788cf35ab 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.

fdc746ac38 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.

LLVM make the very reasonable assumption that constant expressions will
have at least one operand! :)

1c72c28b2b For PR351: 
Use sys::MappedFile instead of ReadFileIntoAddressSpace and
UnmapFileFromAddressSpace. sys::MappedFile has the nice property that it
cleans up after itself so exception handling can be removed.

23b2d6fd82 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.
