a9b7d60d67 Eliminate the static constructors and locks from DynamicLibrary.cpp.
This fixes PR4512 and eliminating static ctors is always good.  Losing
thread safety is unfortunate, but the code is just incredibly poorly
designed.

If someone is interested, the "right" solution is to split
DynamicLibrary.cpp into two separate pieces: a stateless piece in
libsystem, and a simple support file in libsupport that has the
"state" (e.g.  AddSymbol) in managed static objects.

Doing this would both fix memory leaks we already have, as well as make
the code thread safe again.  it would also make sense to move all the
unix specific code in System/DynamicLibrary.cpp into 
System/Unix/DynamicLibrary.inc.

f37feb954f Guard dynamic library loading.
I did my best at implementing this for Win32, but I don't have a way to test it.
Can someone with access to a Win32 machine test/fix this?

d5f1627d2c This is a simple fix for getting error messages from dlerror in
LoadLibraryPermanently. The current code modifies the value of a pointer
that is passed by value, so the caller never gets the message.

needed for output to be generated. On Linux these are both global vars and
macro definitions so we have to special case Linux.

99655e16a6 For PR797:
Final commit for this bug. This removes the last EH holdouts in LLVM
and turns off exception support by using the -fno-exceptions option. This
leads to the following reduction in library and executable sizes:

lib/System available to programs that #include LinkALlVMCore.h so that
loadable modules linked into those programs can depend on all of lib/System
