7e2e555075 Added *hidden* flags -print-options and -print-all-options so 
developers can see if their driver changed any cl::Option's. The
current implementation isn't perfect but handles most kinds of
options. This is nice to have when decomposing the stages of
compilation and moving between different drivers. It's also a good
sanity check when comparing results produced by different command line
invocations that are expected to produce the comparable results.

Note: This is not an attempt to prolong the life of cl::Option. On the
contrary, it's a placeholder for a feature that must exist when
cl::Option is replaced by a more appropriate framework. A new
framework needs: a central option registry, dynamic name lookup,
non-global containers of option values (e.g. per-module,
per-function), *and* the ability to print options values and their defaults at
any point during compilation.

cb1d6e9690 Version N of the llvm_unreachable patch: VC++ doesn't recognize that abort() 
doesn't return, so just go back to using the old runtime function instead
of trying to use abort() when __builtin_unreachable (or an equivalent) isn't
supported.

c6cda9defe Change directory_entry::path() to return a const std::string & instead of 
a StringRef, for the benefit of clients that want the result as a
nul-terminated string. Clients that expect a StringRef will get one via
the implicit conversion.

9f386640da Now that -loop-idiom uses TargetLibraryInfo properly, it doesn't 
need to be pulled out of the pass manager when the user specifies 
-fno-builtin.  It can intelligently determine which libcalls to
optimize based on what is enabled in TargetLibraryInfo.  This 
allows -fno-builtin-foo to work someday.

63f1d56458 switch the constantexpr, target folder, and IRBuilder interfaces

75fafed2fd Add llvm::sys::path::canonical(), which provides the canonicalized 
name of a path, after resolving symbolic links and eliminating excess
path elements such as "foo/../" and "./".

This routine still needs a Windows implementation, but I don't have a
Windows machine available. Help? Please?

7468ab4b90 Rework InstrTypes.h so to reduce the repetition around the NSW/NUW/Exact 
versions of creation functions.  Eventually, the "insertion point" versions
of these should just be removed, we do have IRBuilder afterall.

Do a massive rewrite of much of pattern match.  It is now shorter and less
redundant and has several other widgets I will be using in other patches.
Among other changes, m_Div is renamed to m_IDiv (since it only matches 
integer divides) and m_Shift is gone (it used to match all binops!!) and
we now have m_LogicalShift for the one client to use.

Enhance IRBuilder to have "isExact" arguments to things like CreateUDiv
and reduce redundancy within IRbuilder by having these methods chain to
each other more instead of duplicating code.
