573333530f Tweak MemoryBuffer::getSTDIN so that it returns after the first EOF. 
It doesn't matter for piped input, but it's annoying when typing at the 
console.

588d3d1fd6 Add llvm::Triple class for abstracting access to target triples. 
- The code is silly, I'm just amusing myself. Rewrite to be efficient
   if you like. :)

Also, if you wish to debate the proper names of the triple components
I'm all ears.

770f4158e5 Use CHAR_BIT instead of hard-coding 8 in several places where it 
is appropriate. This helps visually differentiate host-oriented
calculations from target-oriented calculations.

34123aba43 Fix internal representation of fp80 to be the 
same as a normal i80 {low64, high16} rather
than its own {high64, low16}.  A depressing number
of places know about this; I think I got them all.
Bitcode readers and writers convert back to the old
form to avoid breaking compatibility.

7c9dba0950 Add BUILTIN_EXPECT Support/Compiler macro.

   off a cycle or two.

 - Please rename if you have a better one.

b04be1838d raw_ostream: Rework implementation of unbuffered streams so outputting 
a single character requires only one branch to follow slow path.
 - Never use a buffer when writing on an unbuffered stream.

 - Move default buffer size to header.

2062a58347 raw_ostream: Replace flush_impl with write_impl, which takes data to 
write as arguments.
 - Add raw_ostream::GetNumBytesInBuffer.
 - Privatize buffer pointers.
 - Get rid of slow and unnecessary code for writing out large strings.

c2d554fe0b raw_ostream: Lift out flush_nonempty. 
- Flush a known non-empty buffers; enforces the interface to
   flush_impl and kills off HandleFlush (which I saw no reason to be
   an inline method, Chris?).

 - Clarify invariant that flush_impl is only called with OutBufCur >
   OutBufStart.

 - This also cleary collects all places where we have to deal with the
   buffer possibly not existing.

 - A few more comments and fixing the unbuffered behavior remain in
   this commit sequence.

4ee393a21a Fix a hashing bug in APInt. A certain pathological testcase (too 
large for the testsuite) took over six minutes to compile on my Mac.
The patched LLVM-GCC compiles that testcase in three seconds (GCC
takes less than one second).  This hash function is more complex
(about 35 instructions on x86) than what Chris wanted, but I expect it
will be well-behaved with arbitrary inputs.

Thank you to everyone who responded to my previous request for advice.

99b48e57ba Eliminate a 9640 byte static mutable initialized data item by moving it 
to the stack.  This shrinks all llvm tools by 9k, and improves reentrancy.

c4f40d1f53 Daniel wanted the stack printed upside down. Perhaps he 
feels a kinship to machine stacks that grow down.  Now we get
stuff like this:

Stack dump:
0.	Program arguments: clang clang_crash_Iw2Osj.mi 
1.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: parsing function body '_mm_cvtpi16_ps'
2.	/Developer/SDKs/MacOSX10.5.sdk/usr/lib/gcc/i686-apple-darwin9/4.0.1/include/xmmintrin.h:624:1: in compound statement ('{}')

25f2741ae9 The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF. 
Add support for two additional DWARF attributes to encode Objective-C runtime version number.

48be6b5e15 Unbreak the build on win32. 
Cleanup some warning.

Remark: when struct/class are declared differently than they are defined, this make problem for VC++ since it seems to mangle class differently that struct. These error are very hard to understand and find. So please, try to keep your definition/declaration in sync.

Only tested with VS2008. hope it does not break anything. feel free to revert.
