If we spawn an lldb process for test (via pexpect), do not load the init file unless told otherwise.
Set up self.lldbOption to be "--no-lldbibit" unless env variable NO_LLDBIBIT is defined and equals "NO".
Also add "-nx" to gdb spawned.

Re-organized the contents of RangeMap.h to be more concise and also allow for a Range, RangeArray, RangeData (range + data), or a RangeDataArray. We have many range implementations in LLDB and I will be converting over to using the classes in RangeMap.h so we can have one set of code that does ranges and searching  of ranges.

Fixed up DWARFDebugAranges to use the new range classes.

Fixed the enumeration parsing to take a lldb_private::Error to avoid a lot of duplicated code. Now when an invalid enumeration is supplied, an error will be returned and that error will contain a list of the valid enumeration values.

un-breaks every glib-dependent compile with Clang.

I'm not sure this is even the best workaround, so suggestions welcome.

Consider:
  mov r8, r11 fred

Previously, we issued the not very informative:
x.s:6:1: error: unexpected token in argument list

^

Now we generate:
x.s:5:14: error: unexpected token in argument list
  mov r8, r11 fred
              ^

Multidefs are a bit unwieldy and incomplete.  Remove them in favor of
another mechanism, probably for loops.

  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.

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.

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.
