17c95658e6 Pull in r175057 from upstream LLVM, via FreeBSD, found by Wada Hiroyuki. 
X86: Disable generation of rep;movsl when %esi is used as a base pointer.
This happens when there is both stack realignment and a dynamic alloca in the
function. If we overwrite %esi (rep;movsl uses fixed registers) we'll lose the
base pointer and the next register spill will write into oblivion.

df44ab302a Disable PIE for now in clang until someone is masochistic enough to figure 
out how to best handle enabling it by default.  Manually speficying -fpie
-Wl,-pie will still work, of course.

eca8eaed22 Add several CLang patches from upstream via Brad. 
- Only provide /usr/include in the default C header search path.
- OpenBSD does not support TLS.

cf153cacfa Fix libpthread linking (use '-pthread' instead of '-lpthread') for 
cmake-based ports that use "CHECK_LIBRARY_EXISTS(pthread ...)".

Fix libpthread linking for devel/llvm too (additional care was
needed).

No fallout in a bulk build: thanks landry!

e377137feb - don't build Hello sample module, it builds a shared library with 
an odd filename which doesn't get correctly identified by pkg tools,
and isn't really useful to provide in the package anyway
- cnst@ points out this is actually a post-2.4 snapshot, change the
PKGNAME accordingly

136611c6f3 import llvm/clang. not heavily tested yet but there's been a lot 
of interest in the static analyser and it basically works, so put
it in now and link to the build later.

Low Level Virtual Machine (LLVM) is:
- A compilation strategy designed to enable effective program
  optimization across the entire lifetime of a program.
- A virtual instruction set.
- A compiler infrastructure.
- LLVM does not imply things that you would expect from a high-level
  virtual machine. It does not require garbage collection or run-time
  code generation.

some parts from chl@ and the FreeBSD port.
