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.

This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.

 previous cmp; a copy can not be inserted here if the copy insn also has
 side effects. We don't have access to the attributes of copy insn here;
 so just play safe by finding a safe locations for branch terminators.

Finish LLVMContext-ing lib/Analysis.  This required pushing LLVMContext's through the ValueTracking API.

pic16 doesn't have a Data64bitsDirective. Set it NULL explicitly to tell the generic code to not pick the default.

Implement _section macro to allow users to place objects in specific sections.
Implement _address macro to allow users to place objects at a particular address.
Placing objects at a memory address:
crate a unique section name from varname, address, object type and put that section at specified address. Mark this section a full (size = banksize) so that other objects do not compete for it while placing objects to sections in AsmPrinter.
