0afb18f239 llvm-mc/x86: Fix various nit-picky bugs in displacement parsing. 
- Test case to follow.

b87d6f328e llvm-mc/x86: Fix bug in disambiguation of displacement operand, introduced by me 
(I think).
 - We weren't properly parsing the leading parenthesized expression in something
   like 'push (4)(%eax)'.
 
 - Added ParseParenRelocatableExpression to support this. I suspect we should
   just use lookahead, though.

 - Test case to follow.

a key is present in a std::map or DenseMap to use find instead.

4fa7e54329 Make the use of const with respect to LLVMContext sane. Hopefully this is the last time, for the 
moment, that I will need to make far-reaching changes.

29ea777c1e Add a portable strerror*() wrapper, llvm::sys::StrError(). This includes the 
Windows variant, strerror_s, but I couldn't test that.

I'll update configure and config.h.in in a subsequent patch.

81b8dabb53 Add a pointer to the owning LLVMContext to Module. This requires threading LLVMContext through a lot 
of the bitcode reader and ASM parser APIs, as well as supporting it in all of the tools.

Patches for Clang and LLVM-GCC to follow.

5bec168037 Normalize SourceMgr messages. 
- Don't print "Parsing" in front of every message.

 - Take additional "type" argument which is prepended to the message (with ": ")

37b8fe7db3 llvm-mc: Diagnose misuse (mix) of defined symbols and labels. 
- For example, we diagnose errors on:
--
a:
a = 10
--

 - For now we reject code like:
--
.long a
a = 10
--
   which "as" accepts (on Darwin).

c431f61520 Add a JITEventListener interface that gets called back when a new function is 
emitted or the machine code for a function is freed.  Chris mentioned that we
may also want a notification when a stub is emitted, but that'll be a future
change.  I intend to use this to tell oprofile where functions are emitted and
what lines correspond to what addresses.
