and using the latter in DIBuilder::createArtificialType and
DIBuilder::createObjectPointerType methods as well as introducing
mirroring DISubprogram::cloneWithFlags and
DIBuilder::createArtificialSubprogram methods.
The primary goal here is to add createArtificialSubprogram to support
a pass downstream while keeping the method consistent with the
existing ones and making sure we don't encourage changing already
created DI-nodes.

This is a simple implementation of the unroll-and-jam classical loop
optimisation.
The basic idea is that we take an outer loop of the form:
for i..
ForeBlocks(i)
for j..
SubLoopBlocks(i, j)
AftBlocks(i)
Instead of doing normal inner or outer unrolling, we unroll as follows:
for i... i+=2
ForeBlocks(i)
ForeBlocks(i+1)
for j..
SubLoopBlocks(i, j)
SubLoopBlocks(i+1, j)
AftBlocks(i)
AftBlocks(i+1)
Remainder
So we have unrolled the outer loop, then jammed the two inner loops into
one. This can lead to a simpler inner loop if memory accesses can be shared
between the now-jammed loops.
To do this we have to prove that this is all safe, both for the memory
accesses (using dependence analysis) and that ForeBlocks(i+1) can move before
AftBlocks(i) and SubLoopBlocks(i, j).

D47308 has been merged in r333206, the OSX issue should now be

In many cases JIT users will know in which module a symbol
resides. Avoiding to search other modules can be more efficient. It

This reverts r333147 until https://reviews.llvm.org/D47308 is ready to
be reviewed. r333147 exposed a behavioural difference between
OrcCBindingsStack::findSymbolIn() and OrcCBindingsStack::findSymbol(),
where only the latter does name mangling. After r333147 that causes a
test failure on OSX, because the new test looks for main using
findSymbolIn() but the mangled name is _main.

Support includes this header for the typedefs - but logically it's part
of the MC/Disassembler library that implements the functions. Split the
header so as not to create a circular dependency.
This is another case where probably inverting the llvm-c implementation
might be best (rather than core llvm libraries implementing the parts of
llvm-c - instead llvm-c could be its own library, depending on all the
parts of LLVM's core libraries to then implement llvm-c on top of
them... if that makes sense)
llvm-svn: 328744
Compiler.h is used by Demangle (which Support depends on) - so sink it
into Demangle to avoid a circular dependency
DataTypes.h is used by llvm-c (which Support depends on) - so sink it
into llvm-c.
DataTypes.h could probably be fixed the other way - making llvm-c depend
on Support instead of Support depending on llvm-c - if anyone feels
that's the better option, happy to work with them on that.
I /think/ this'll address the layering issues that previous attempts to
commit this have triggered in the Modules buildbot, but I haven't been
able to reproduce that build so can't say for sure. If anyone's having
trouble with this - it might be worth taking a look to see if there's a
quick fix/something small I missed rather than revert, but no worries.

Support depends on llvm-c (a few typedefs, macros, etc - Types.h,
Disassembler.h, and TargetMachine.h.
This could be done the other way - those macros/typedefs/etc could be

a better direction to go, happy to discuss it/try it out/etc.
