I'm reverting one of the changes made to exception.cpp in r151717.  I'm unsure what the change was trying to do, but it didn't do the right thing for __APPLE__.  So instead of trying to guess what was intended, I'm just putting it back the way it was.

Note: This depends on an xlocale (partial) implementation for Solaris and a

an unwind because RegisterContextLLDB::InitializeZerothFrame() would
create a minimal stack frame to fetch the pc value of the current
instruction.  This proved fragile when another section of code was
trying to create the first stack frame and UnwindLLDB called
RegisterContextLLDB which tried to create its minimal stack frame.

Instead, get the live RegisterContext, retrieve the pc value from
the registers, and create an Address object from that.

The bug that was caught by Apple's internal buildbots was valid and also showed another bug in my implementation.

These are now fixed, with regression tests added to catch them both (not Darwin-specific).

Original log:
====================

Revert r151638 because it causes assertion hit on PCH creation for Cocoa.h

Original log:
---------------------
Correctly track tags and enum members defined in the prototype of a function, and ensure they are properly scoped.

This fixes code such as:

enum e {x, y};
int f(enum {y, x} n) {
 return 0;
}

This finally fixes PR5464 and PR5477.
---------------------

I also reverted r151641 which was enhancement on top of r151638.

[analyzer] Tweak the UnreachableCode checker to not warning about unreachable default blocks.  Patch by Cyril Roelandt!

Added the ability to override command line commands. In some cases GUI interfaces
might want to intercept commands like "quit" or "process launch" (which might cause
the process to re-run). They can now do so by overriding/intercepting commands
by using functions added to SBCommandInterpreter using a callback function. If the
callback function returns true, the command is assumed to be handled. If false
is returned the command should be evaluated normally.

Adopted this up in the Driver.cpp for intercepting the "quit" command.

 a) adds a Python summary provider for NSDate
 b) changes the initialization for ScriptInterpreter so that we are not passing a bulk of Python-specific function pointers around
 c) provides a new ScriptInterpreterObject class that allows for ref-count safe wrapping of scripting objects on the C++ side
 d) contains much needed performance improvements:
    1) the pointer to the Python function generating a scripted summary is now cached instead of looked up every time
    2) redundant memory reads in the Python ObjC runtime wrapper are eliminated
    3) summaries now use the m_summary_str in ValueObject to store their data instead of passing around ( == copying) an std::string object
 e) contains other minor fixes, such as adding descriptive error messages for some cases of summary generation failure

of the SmallPtrSet way up to avoid commonly reallocating the buffer size.
 - I didn't see a good argument against it, so I bumped the limit to cover the
   max size we see during parsing Cocoa.h.

 - This reduces our total # of allocations building a PCH for Cocoa.h by almost
   a whopping 50%.
 - A SmallPtrMap would be cleaner, but since we don't have one yet...

[Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ST_Undefined. Implement these completely for ELF.
Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type
is unknown, not that the symbol is undefined. (For that, use ST_Undefined).

This transformation is not correct for not-equal conditions:

(trunc x) != C1 & (and x, CA) != C2 -> (and x, CA|CMAX) != C1|C2

Let
  C1 == 0
  C2 == 0
  CA == 0xFF0000
  CMAX == 0xFF
and truncating to i8.

The original truth table:

    x   | A: trunc x != 0 | B: x & 0xFF0000 != 0 | A & B != 0
--------------------------------------------------------------
0x00000 |        0        |          0           |     0
0x00001 |        1        |          0           |     0
0x10000 |        0        |          1           |     0
0x10001 |        1        |          1           |     1

The truth table of the replacement:

    x   | x & 0xFF00FF != 0
----------------------------
0x00000 |        0
0x00001 |        1
0x10000 |        1
0x10001 |        1

So they are different.

This function does more or less the same as
MI::readsWritesVirtualRegister(), but it supports bundles as well.

It also determines if any constraint requires reading and writing
operands to use the same register.  Most clients want to know.

Use the more modern MO.readsReg() instead of trying to sort out undefs
and partial redefines.  Stop supporting the extra full <imp-def> operand
as an alternative to <def,undef> sub-register defines.
