Always use binary mode for output stream. This is important to prevent unwanted end of line conversion on Windows. Should not affect Unix where O_BINARY is not defined. This fix /clang/test/lexer/preamble.c XFAIL on WIN32.

Begin adding static dependence information to passes, which will allow us to

perform initialization without static constructors AND without explicit initialization
by the client. For the moment, passes are required to initialize both their
(potential) dependencies and any passes they preserve. I hope to be able to relax
the latter requirement in the future.

After splitting, the remaining LiveInterval may be fragmented into multiple

connected components. These components should be allocated different virtual
registers because there is no reason for them to be allocated together.
Add the ConnectedVNInfoEqClasses class to calculate the connected components,
and move values to new LiveIntervals.

components.
