Reverting r76825 and r76828, since they caused clang runtime errors and some build failure involving memset.

out of memory, and also make the default memory manager allocate more memory
when it runs out.

Also, switch function stubs and global data over to using the BumpPtrAllocator.

This makes it so the JIT no longer mmaps (or the equivalent on Windows) 16 MB
of memory, and instead allocates in 512K slabs.  I suspect this size could go
lower, especially on embedded platforms, now that more slabs can be allocated.

Implemented by moving the code out of static functions into methods of Program
class.

 - Minor tweak by me to add llvm_unreachable calls on FIXMEd error paths.

"UNIX paths can contain non-ASCII characters, so Path::isValid() should not reject paths with such characters in them. The attached patch removes the check from Path::isValid()."

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.

I'll update configure and config.h.in in a subsequent patch.

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?
