Robert Lytton 9715375c25 XCore target: fix bug in XCoreLowerThreadLocal.cpp 
When a ConstantExpr which uses a thread local is part of a PHI node
instruction, the insruction that replaces the ConstantExpr must
be inserted in the predecessor block, in front of the terminator instruction.
If the predecessor block has multiple successors, the edge is first split.

Rui Ueyama f1e266846d Remove excessive allowRemainingUndefines() check. 
allowRemainingUndefines() is already checked in Resolver::resolve(), so we
don't need to check it again after returning from it. It's actually not only
superfluous but buggy because a failure of resolve() does not always mean that
there is a remaining undefines.

Ed Maste 04a8bab047 Support mips shared object debug info 
MIPS's .dyanamic section is read-only.  Instead of using DT_DEBUG for
the pointer to dyld information it uses a separate tag DT_MIPS_RLD_MAP
which points to storage in the read-write .rld_map section, which in
turn points to the dyld information.

Matthias Braun d7df935bbc Refactor LiveInterval: introduce new LiveRange class 
LiveRange just manages a list of segments and a list of value numbers
now as LiveInterval did previously, but without having details like spill
weight or a fixed register number.
LiveInterval is now a subclass of LiveRange and simply adds the spill weight
and the register number.

Tom Stellard 6c7b86c106 Implement nextafter() builtin 
There are two implementations of nextafter():
1. Using clang's __builtin_nextafter.  Clang replaces this builtin with
a call to nextafter which is part of libm.  Therefore, this
implementation will only work for targets with an implementation of
libm (e.g. most CPU targets).

2. The other implementation is written in OpenCL C.  This function is
known internally as __clc_nextafter and can be used by targets that
don't have access to libm.
