Headers: add hint intrinsics to arm_acle.h

This adds the ARM ACLE hint intrinsic wrappers to arm_acle.h.  These need to be
protected with a !defined(_MSC_VER) since MSVC (and thus clang in compatibility
mode) provide these wrappers as proper builtin intrinsics.

MS ABI: Stick internal vftables in a comdat if they have RTTI data

Previously, we would have a private backing variable and an internal
alias pointing at it.

However, -fdata-sections only fires if a global variable has non-private
linkage.  This means that an unreferenced vftable wouldn't get
discarded, bloating the object file.

Instead, stick the backing variable in a comdat even if the alias has
internal linkage.  This will allow the linker to drop the vftable if it
is unused.

Superficial fix for PR20218: binding a function lvalue to a const reference to
a function pointer is neither better nor worse than binding a function lvalue
to a function rvalue reference. Don't get confused and think that both bindings
are binding to a function lvalue (which would make the lvalue form win); the
const reference is binding to an rvalue.

The "real" bug in PR20218 is still present: we're getting the wrong answer from
template argument deduction, and that's what leads us to this weird overload
set.

ARM: Implement __builtin_arm_nop intrinsic

This patch implements __builtin_arm_nop intrinsic for AArch32 and AArch64,
which generates hint 0x0, the alias of NOP instruction.

This intrinsic is necessary to implement ACLE __nop intrinsic.

Change the diagnostic group for unsupported gcc optimizations added r212805

Use -Winvalid-command-line-argument here to align with existing gcc opt

Also tweak wording to make sense with -Werror.
