ff25f858fd Let the strcat optimizer return the pointer to the start of the buffer, 
instead of the place where it started to perform the string copy.

14d86f7755 Map stack based frameindices for spills to zero based indices that can be accessed based on an external symbol defining the location of temporary data for a function. For example: we have spill slots addressed as foo.tmp + 0, foo.tmp + 1 etc.

2da28965f6 CMake: defines and uses macro add_llvm_definitions for keeping track 
of compiler parameters explicitly added by the build
specification. This macro replaces the cmake built-in
`add_definitions'.

Detects glibc and defines _GNU_SOURCE accordingly.

Resolves bug 3882.

eea5412e19 Add support for embedded metadata to LLVM. This introduces two new types of 
Constant, MDString and MDNode which can only be used by globals with a name
that starts with "llvm." or as arguments to a function with the same naming
restriction.

7c98197368 Add fast path for raw_ostream output of strings. 
- Particularly nice for small constant strings, which get optimized
   down nicely. On a synthetic benchmark writing out "hello" in a
   loop, this is about 2x faster with gcc and 3x faster with
   llvm-gcc. llc on insn-attrtab.bc from 403.gcc is about .5% faster.

 - I tried for a fancier solution which wouldn't increase code size as
   much (by trying to match constant arrays), but can't quite make it
   fly.

1555a0a503 Params are not being generated as static globals now. The caller passes them onto the callee's stack directly and the callee loads the argvals from its own stack. Clang generated frameindexes validatd by recalculating the stack as if all frameindexes represent 1-byte slots.

09cab2de98 fix overflow checks in SmallVector: 
"The code was doing "if (End+NumInputs > Capacity) ...". If End is
close to 0xFFFFFFFF and NumInputs is large, it'll overflow, the
condition will come out false, and the vector won't grow to
accommodate the new elements, and the program will crash in memmove."

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.
