Revert part of r141274. Only need to change encoding for xchg %eax, %eax in 64-bit mode. This is because in 64-bit mode xchg %eax, %eax implies zeroing the upper 32-bits of RAX which makes it not a NOP. In 32-bit mode using NOP encoding is fine.

Since we use address ranges a lot I added a templatized class that allows us to easily control the base address type, the size type, and the data that is stored with each range. It is designed to be populated by appending all needed items, then sorting the resulting list, and optionally minimizing the list when done. I adopted this new list in the DWARFDebugAranges for even further memory savings.

aggressively emit the IR translation of a record during its
own definition.  Fixes PR10912.

Fixed the root cause of what was causing an assertion to fire during single stepping. We had an issue with the inlined stack frames where when we had inlined frames that were not in the first concrete frame where we passed the wrong PC down. We needed to decrement the PC by one for these frames to make
sure we are using the same address that did the symbol context lookup.

then jumps to the correct call site via a jump table.

Fix the check for nested IT instructions in the disassembler.  We need to perform the check before adding the Thumb predicate, which pops on entry off the ITBlock queue.

Fixed an assertion that was causing a crash. The bug describes a case where we have an inlined block that doesn't contain the frame PC that was used to lookup the symbol context in the first place. This really shouldn't happen, so
now we log if we run into this and don't assert.

Support for C1x _Atomic specifier (see testcase).  This is primarily being committed at the moment to help support C++0x <atomic>, but it should be a solid base for implementing the full specification of C1x _Atomic.
