This cuts down the number on system calls done by a static llvm-ar producing
lib/libclangSema.a from 9164 to 442.

These are fake and not actual PCs, more like function IDs.

We already have them mapped into memory, so we can just close the file.

This should fix PR21878.

Properly determine whether or not a phi was added by splitting.
Check against the current VNInfo of OrigLI instead of against the
OrigVNI argument.

Extract the creation of overflow result tuples in a separate function. NFC.

Just use the Module unique_ptr object directly in many places instead of separate pointer that's kept in sync with it.

Canonicalize formatting of metadata to make it easier to upgrade via
scripts -- in particular, one line per metadata definition makes it more
`sed`-able.

This is preparation for changing the assembly syntax for metadata [1].

Reverting commit 223981, because the test that I added (incorrect-variable-debugloc1.ll) failed for llvm-ppc64.

The test is failing for llvm-ppc64 because for this platform the location list is not being generated at all (most likely because of the bug in PPC code optimization or generation). I will file a bug agains PPC compiler, but meanwhile, until PPC bug is fixed, I will have to revert my change.

Replace std::map<K, V*> with std::map<K, std::unique_ptr<V>> to handle ownership and deletion of the values.

Ideally we would store the MultiClasses by value directly in the maps, but I had some trouble with that before and this at least fixes the leak.

llvm-svn: 223997

We can't reach those from zext, but other parts of the backend (the shuffle
lowering) generate 256-bit VZEXT nodes.

Fixes PR21876.

This change moves the ownership and access of GCFunctionInfo (the object which describes the safepoints associated with a safepoint under GCRoot) to GCModuleInfo. Previously, this was owned by GCStrategy which was in turned owned by GCModuleInfo. This made GCStrategy module specific which is 'surprising' given it's name and other purposes.

There's a few more changes needed, but we're getting towards the point we can reuse GCStrategy for gc.statepoint as well.

p.s. The style of this code ends up being a mess. I was trying to move code around without otherwise changing much. Once I get the ownership structure rearranged, I will go through and fixup spacing, naming, comments etc.

Take the opportunity to sort these by `metadata`.

While we would correctly handle asm("foo") and reject asm(L"bar"), we
weren't careful to handle cases where an ascii literal could be
concatenated with a wide literal.

This fixes PR21822.

I apparently fail at the alphabet, E is not after G, and G isn't even
