Add a facility for invoking the llvm-config tool when linking a program.
This facility allows LLVMLIBS to be specified with something like:
LLVMLIBS = config --libs jit
instead of:
LLVMLIBS = JIT
with the same effect. However, the llvm-config utility is much more versatile
than the single keyword approach. Note that "config" is the keyword after
which any arguments to llvm-config are allowed. When llvm-config is tested
and working well, we'll start using this and drop support for the JIT
keyword.

Update to llvm-config tool, by Erik Kidd:

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.

This version is now ready for testing by users.

These changes are necessary to support the new llvm-config tool. llvm-config
is a handy tool for users of LLVM who want to be able to quickly get
information about LLVM's configuration. It is intended to be used in the
command line of other tools. Documentation will be forthcoming in a
subsequent patch.

- VECTOR_SHUFFLE of v4i32 / v4f32 with undef second vector always matches

  anything we want.
- Change some names to appease Chris.
