This is the first step in adding sane error handling support to LLVMSystem.
The system API's will be shifted over to returning an error_code, and returning
other return values as out parameters to the function.
Code that needs to check error conditions will use the errc enum values which
are the same as the posix_errno defines (EBADF, E2BIG, etc...), and are
compatable with the error codes in WinError.h due to some magic in system_error.
An example would be:
if (error_code ec = KillEvil("Java")) { // error_code can be converted to bool.
handle_error(ec);

In which I discover the existence of loops. Threading an operation
over a phi node by applying it to each operand may be wrong if the
operation and the phi node are mutually interdependent (the testcase
has a simple example of this). So only do this transform if it would
be correct to perform the operation in each predecessor of the block
containing the phi, i.e. if the other operands all dominate the phi.
