9ae3dee83e Stop llvm-config thinking that there are circular 
dependencies between libraries due to __dso_handle
when doing "make install".  I don't know what the
LINK_COMPONENTS stuff is about, so I left it alone.

d8f77bbc07 if we have a large GEP offset on a 32-bit or other target, make 
sure to print the value properly sext'd to the right pointer size.
This fixes PR3481.

902d570061 Pre-alloc splitting needs to be more careful to avoid inserting spills/restores 
between call frame setup/restore points.  Unfortunately, this regresses 
code size a bit, but at least it's correct now!

7c25f31e98 It's not obvious, but lto_module_create_from_memory doesn't need to use the 
buffer after it creates the Module. Thus, we don't need to store this pointer
in claimed_file.

66f10b55ed New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.

83f8f82e8a Avoids generating a legalization assert for the case where a vector type is legal 
but when legalizing the operation, we split the vector type and generate a library
call whose type needs to be promoted. For example, X86 with SSE on but MMX off, 
a divide v2i64 will be scalarized to 2 calls to a library using i64.

9d89863489 Since I'm obliged to work with a development OS that currently doesn't 
support GraphViz, I've been using the foo->dump() facility.  This
patch is a minor rewrite to the SelectionDAG dump() stuff to make it a
little more helpful.  The existing foo->dump() functionality does not
change; this patch adds foo->dumpr().  All of this is only useful when
running LLVM under a debugger.

d80609a7b3 Don't bother hoisting out a "cheap" instruction if all of its uses are PHIs. LICM "cheap" instructions are not particularly beneficial to start with. This will just end up making the copies harder to coalesce.

68f918e570 For now, only hoist re-materilizable instructions. LICM will increase register pressure. We want to avoid spilling more instructions if it's possible.

a9c6af0bb8 Reapply patch from r62553, with a fix to avoid looking for an ffi.h that isn't 
there.

This changes the interpreter to use libffi. After this patch, the interpreter
will barely be able to call any external functions if built on a system without
libffi installed (just enough to pass 'make check' really). But with libffi,
we can now call any function that isn't variadic or taking a struct or vector
parameter (but pointer to struct is fine). Patch by Alexei Svitkine!
