TARGET_HAS_JIT flag is checked.

Looks like cmake on windows is not expanding ENABLE_EXPORTS to
-Wl,--export-all-symbols on mingw or cygwin, so add this back.

llvm-svn: 178730

On freebsd this makes sure that symbols are exported on the binaries that need
them. The net result is that we should get symbols in the binaries that need
them on every platform.

On linux x86-64 this reduces the size of the bin directory from 262MB to 250MB.

Patch by Stephen Checkoway.

This generalizes Optional to require less from the T type by using aligned
storage for backing & placement new/deleting the T into it when necessary.

Also includes unit tests.

PR15138 was opened because of a segfault in the Bitcode writer.
The actual issue ended up being a bug in APInt where calls to
APInt::getActiveWords returns a bogus value when the APInt value
is 0.  This patch fixes the problem by ensuring that getActiveWords
returns 1 for 0 valued APInts.
