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.

72501b4a21 remove dead code, noone creates instances of "DynamicLibrary", so the ctor and dtor are dead.

7ed47a1335 Don't attribute in file headers anymore. See llvmdev for the
discussion of this change.  Boy are my fingers tired. ;-)

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:

23dd3327a0 For PR780:
Put the rest of lib/System into LinkAllVMCore.h. This makes all of
lib/System available to programs that #include LinkALlVMCore.h so that
loadable modules linked into those programs can depend on all of lib/System
being available.

85046901b8 Add AddSymbol() method to DynamicLibrary to work around Windows limitation
of being unable to search for symbols in an EXE.  It will also allow other
existing hacks to be improved.

b0b0ea07bb Add in some methods for use by the JIT. LoadLibraryPermanently brings the
library into the address space permanently. SearchForAddressOfSymbol looks
in all previously permanently loaded libraries and any currently open
libraries for a symbol, instead of just one library like GetAddressOfSymbol

0de02a6ba9 Dynamic Library abstraction. This makes the abstraction of a single dynamic
library (shared library/shared object) whose symbols can be looked up
dynamically. Used for plug-ins.
