Add predicates for checking whether targets have free FNEG and FABS operations, and prevent the DAGCombiner from turning them into bitwise operations if they do.

Fix potential null dereference in the static analyzer when inlining a call that has already been inlined.  Unfortunately I have no test case.

Export the ability to see if a symbol is externally visible and also if the symbol was synthetically added to the symbol table (the symbol was not part of the symbol table itself but came from another section).

This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.

The test case checks for both big and little endian flavors.

The diagnostic message correctly informs the user that they have omitted the
'class' keyword, but neither suggests this insertion as a fixit, nor attempts
to recover as if they had provided the keyword.

This fixes the recovery, adds the fixit, and adds a separate diagnostic and
corresponding replacement fixit for cases where the user wrote 'struct' or
'typename' instead of 'class' (suggested by Richard Smith as a possible common
mistake).

I'm not sure the diagnostic message for either the original or new cases feel
very Clang-esque, so I'm open to suggestions there. The fixit hints make it
fairly easy to see what's required, though.

not by canonical decl. This only matters for sizeof...(Pack) expressions; in
all other cases, we'd profile it as a type instead.

move constructor/move assignment operator are not declared, rather than being
defined as deleted, so move operations on the derived class fall back to
copying rather than moving.

If a move operation on the derived class is explicitly defaulted, the
unmovable subobject will be copied instead of being moved.

We have not trivial way for splitting edges that are goes from indirect branch. We can do it with some tricks, but it should be additionally discussed. And it is still dangerous due to difficulty of indirect branches controlling.

Fix forbids this case for unswitching.

reflected in the LLVM IR (as a declare or something), then treat it like a data
object.

N.B. This isn't 100% correct. The ASM parser should supply more information so
that we know what type of object it is, and what attributes it should have.

Reorder fields in MatchEntry and OperandMatchEntry to reduce padding. A bit tricky due to the target specific sizes for some of the fields so the ordering is only optimal for the targets in the tree.

Do not try to optimize swizzles of shuffles if the source shuffle has more than
a single user, except when the source shuffle is also a swizzle.
