Tobias Grosser e19661e0ca ScopInfo: Some cleanups 
- Use __isl_give and __isl_take
- Convert variables to start with Uppercase letter
- Only assign the 'domain' after it is fully constructed
- Only name it after it is fully constructed

Duncan Sands c52af46484 Teach GVN to also propagate switch cases. For example, in this code 
switch (n) {
    case 27:
      do_something(x);
    ...
  }
the call do_something(x) will be replaced with do_something(27).  In
gcc-as-one-big-file this results in the removal of about 500 lines of
bitcode (about 0.02%), so has about 1/10 of the effect of propagating
branch conditions.

Craig Topper 5aebebe18d 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.

Greg Clayton c26e445403 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.

John McCall 0710e551ef Record layout requires not just a definition, but a complete 
definition.  Assert this.  Change IR generation to not try to
aggressively emit the IR translation of a record during its
own definition.  Fixes PR10912.

Greg Clayton 5f4c61e2d7 <rdar://problem/10226227> 
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.

Bill Wendling b3d4678877 Generate the dispatch code for a 'thumb' function. This is very similar to the 
others. They take the call site value. Determine if it's a proper value. And
then jumps to the correct call site via a jump table.

Greg Clayton 70a11261ac <rdar://problem/10226227> 
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.
