BuildSchedGraph was quadratic in the number of calls in the basic
block. After this fix, it keeps only a single call at the top of the
DefList so compile time doesn't blow up on large blocks. This reduces
postRA sched time on an external test case from 81s to 0.3s.  Although
r130800 (reduced ARM register alias defs) also partially fixes the
issue by reducing the constant overhead of checking call interference
by an order of magnitude.

Fixes <rdar://problem/7662664> very poor compile time with post RA scheduling.

I tested both gdb on a bootstrapped clang and and the gdb testsuite on OS X (snow leopard)
and both are happy using __eh_frame.

Many LLVM tests relies on standard output stream be in the binary mode. Which is not always the case (on Windows in particular). The patch adds a test to verify that the standard output stream is actually in the binary mode.

Avoid extra vreg copies for arguments passed in registers.  Specifically, this can make MachineCSE more effective in some cases (especially in small functions).  PR8361 / part of rdar://problem/8259436 .

the overloading of member and non-member functions results in arity
mismatches that don't fit well into our overload-printing scheme. This
only happens for invalid code (which breaks the arity invariants for
these cases), so just suppress the diagnostic rather than inventing
anything new. Fixes <rdar://problem/9222009>.
