Summary: Clang's intrinsic header currently tries to negate the third operand of a vfmadd mask3 in order to create vfmsub, but this fails isel. This patch adds scalar vfmsub and vfnmsub mask3 that we can use instead to avoid the negate. This is consistent with the packed instructions.

Usage:

  llvm-xray extract <object file> [-o <filename or '-'>]

The tool gets the XRay instrumentation map from an object file and turns
it into YAML.  We first support ELF64 sleds on x86_64 binaries, with
provision for supporting other supported platforms and formats later.

This is the first of a many-part change to fully implement the
`llvm-xray` tool.

We also define a subcommand registration and dispatch mechanism to be
used by other further subcommand implementations for llvm-xray.

headers. We previously got this check backwards and treated the wrapper header
as being textual.

This is important because our wrapper headers sometimes inject macros into the
system headers that they #include_next, and sometimes replace them entirely.

Not all echo commands support "-e". On the other hand, printf
command is in POSIX, so it's more portable than "echo -e".

This has the following ABI impact:

 1) Functions whose parameter or return types are non-throwing function pointer
    types have different manglings in c++1z mode from prior modes. This is
    necessary because c++1z permits overloading on the noexceptness of function
    pointer parameter types. A warning is issued for cases that will change
    manglings in c++1z mode.

 2) Functions whose parameter or return types contain instantiation-dependent
    exception specifications change manglings in all modes. This is necessary
    to support overloading on / SFINAE in these exception specifications, which
    a careful reading of the standard indicates has essentially always been
    permitted.

Note that, in order to be affected by these changes, the code in question must
specify an exception specification on a function pointer/reference type that is
written syntactically within the declaration of another function. Such
declarations are very rare, and I have so far been unable to find any code
that would be affected by this. (Note that such things will probably become
more common in C++17, since it's a lot easier to get a noexcept function type
as a function parameter / return type there.)

This change does not affect the set of symbols produced by a build of clang,
libc++, or libc++abi.

Instead of storing a pointer, store the members we need.

The reason for doing this is that it makes it far easier to create
synthetic sections. It also avoids reading data from files multiple
times., which might help with cross endian linking and host
architectures with slow unaligned access.

There are obvious compacting opportunities, but this already has mixed
results even on native x86_64 linking.

There is also the possibility of better refactoring the code for
handling common symbols, but this already shows that a custom class is
not necessary.

Summary:
Fixes PR28281.

MSVC lists indirect virtual base classes in the field list of a class.
This change makes Clang emit the information necessary for LLVM to
emit such records.
