b121bfcc22 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.

fb32507d09 Okay, some compilers complain if you provide the exception-specification
where none was before.  Just don't declare it and hope it's declared
in every translation unit that needs it.

builds, which was the apparent consensus of PR8973 and llvmdev.

10d3191cf1 Remove deprecated macro names. Hopefully this will unbreak the
smooshlab build.  The breakage seems to be due to a collision
between LLVM's ATTRIBUTE_UNUSED and gcc's which was previously
hidden due to header files being included in a lucky order.

97816e1bad Remove LLVM_GLOBAL_VISIBILITY, which is unused, and was not working properly.
The problem was that the test for whether a compiler supports it or not was
inaccurate, but has to be accurate: LLVM_LOCAL_VISIBILITY is an optimization
and not needed for correctness, so wrongly thinking a compiler doesn't support
it is not a big deal, but LLVM_GLOBAL_VISIBILITY is for correctness, and not
an optimization: getting it wrong is fatal: it needs to be set based on a
configure test not testing the gcc version.  Since dragonegg has moved to a
different scheme, and it was the only user of LLVM_GLOBAL_VISIBILITY, just
remove this macro.

16d8f8bd91 I got tired of VISIBILITY_HIDDEN colliding with the gcc enum. Rename it
to LLVM_LIBRARY_VISIBILITY and introduce LLVM_GLOBAL_VISIBILITY, which is
the opposite, for future use by dragonegg.

14c85cbf54 don't use always_inline with gcc 3.4, it has some unimplemented features
and is too old to really care about the performance of the generated 
compiler.

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.

8dc071a6e5 Following a suggestion of Daniel Dunbar, stop people passing the name
as the isSigned bool to CreateIntCast by having this resolve to a call
to a private method, rather than by using a gcc attribute.

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*.

forward declaration and patching tblgen to emit it right. Patch by Amine Khaldi!

31e2466f15 Introduce new error handling API.
This will replace exit()/abort() style error handling with an API
that allows clients to register custom error handling hooks.
The default is to call exit(1) when no error handler is provided.
