a53cfd16f0 split code that doesn't need to be templated out of IRBuilder into a new
non-templated IRBuilderBase class.  Move that large CreateGlobalString
out of line, eliminating the need to #include GlobalVariable.h in IRBuilder.h

079b6f5ee5 Add an "ATTRIBUTE_UNUSED" macro (and use it). It's for variables which are
mainly used in debugging and/or assert situations. It should make the compiler
and the static analyzer stop nagging us about them.

b5d568cc70 Provide dbgs(), a circular-buffering debug output stream. By default it
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.

e59011e7d9 Add circular_raw_ostream, which buffers its output in a circular queue
and outputs it when explicitly flushed.  The intent is to use it in
situations such as debug output logging where a signal handler can take
care of flushing the buffer at program termination.

7b1eb8a409 Remove uber-gross hack. The define _snprintf to snprintf is invalid due to two reasons: 1. Accroding to C++ standard snprintf should be available in std namespace (and __gnu_cxx in case of GCC to). Such ifdef will change all snprintf's to _snprintf's, but won't bring snprintf to all necessary namespaces. Thus e.g. any locale-using code on mingw will yield an error (include this file + string to see the result) 2. MSVCRT's _snprintf does not comply with C99 standard. Standard one is snprintf.

cd0129f5a6 Make some methods const. The only interesting change here is that
it changes raw_fd_ostream::preferred_buffer_size to return zero on
a scary stat failure instead of setting the stream to an error state.
This method really should not mutate the stream.

acts like a pod, not whether it really is a pod.

c500566d9f Only print edgeSourceLabels if they are not empty
Graphviz can layout the graphs better if a node does not contain source
ports. Therefore only print the ports if the source ports are useful,
that means are not labeled with the empty string "".
This patch also simplifies graphs without any edgeSourceLabels e.g. the
dominance trees.

4007324b58 Make sure that if anyone passes a name by accident for the isSigned
parameter of CreateIntCast then they get an error from the compiler
(or from the linker with a non-gcc compiler).  Another possibility
is to flip the order of the DestTy and isSigned parameters, since you
should then get a compiler warning if you try to use a char* for a
Type*.

81cf432569 Fix DenseMap iterator constness.
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

Patch by Victor Zverovich!
