Jakob Stoklund Olesen 25a404eb81 Include a source location when complaining about bad inline assembly. 
Add a MI->emitError() method that the backend can use to report errors
related to inline assembly. Call it from X86FloatingPoint.cpp when the
constraints are wrong.

This enables proper clang diagnostics from the backend:

$ clang -c pr30848.c
pr30848.c:5:12: error: Inline asm output regs must be last on the x87 stack
  __asm__ ("" : "=u" (d));  /* { dg-error "output regs" } */

Jakob Stoklund Olesen 30a8563a61 Use a new strategy for preventing eviction loops in RAGreedy. 
Every live range is assigned a cascade number the first time it is
involved in an eviction. As the evictor, it gets a new cascade number.
Every evictee is assigned the same cascade number as the evictor.

Eviction is prohibited if the evictor has a lower assigned cascade
number than the evictee.

This means that assigned cascade numbers are monotonically increasing
with every eviction, yet they are bounded by NextCascade which can only
be incremented by new live ranges. Thus, infinite loops cannot happen,
but eviction cascades can still be triggered by new live ranges as we
want.

Thanks to Andy for explaining this to me.

Johnny Chen 73a44f6b99 Furnish some docstrings to be swigified into the generated lldb.py module. 
Especially SBProcess.ReadMemory() and SBProcess.WriteMemory() because the generated autodoc strings
make no sense for Python programmers due to typemap (see lldb.swig).
