Major calling convention code refactoring.
...
Instead of awkwardly encoding calling-convention information with ISD::CALL,
ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering
provides three virtual functions for targets to override:
LowerFormalArguments, LowerCall, and LowerRet, which replace the custom
lowering done on the special nodes. They provide the same information, but
in a more immediately usable format.
This also reworks much of the target-independent tail call logic. The
decision of whether or not to perform a tail call is now cleanly split
between target-independent portions, and the target dependent portion
in IsEligibleForTailCallOptimization.
This also synchronizes all in-tree targets, to help enable future
refactoring and feature work.

Don't flush the raw_ostream between each MachineFunction. These flush
...
calls were originally put in place because errs() at one time was
not unbuffered, and these print routines are commonly used with errs()
for debugging. However, errs() is now properly unbuffered, so the
flush calls are no longer needed. This significantly reduces the
number of write(2) calls for regular asm printing when there are many
small functions.
