The "const" pointer typedefs such as "__node_const_pointer" and
"__node_base_const_pointer" are identical to their non-const pointer types.
This patch changes all usages of "const" pointer type names to their respective
non-const typedef.
Since "fancy pointers to const" cannot be converted back to a non-const pointer
type according to the allocator requirements it is important that we never
actually use "const" pointers.
Furthermore since "__node_const_pointer" and "__node_pointer" already
name the same type, it's very confusing to use both names. Especially
when defining const/non-const overloads for member functions.

This patch is very similar to r260431.
This patch is the first in a series of patches that's meant to better
support map. map has a special "value_type" that
differs from pair<const Key, Value>. In order to meet the EmplaceConstructible
and CopyInsertable requirements we need to teach __tree about this
special value_type.
This patch creates a "__tree_node_types" traits class that contains
all of the typedefs needed by the associative containers and their iterators.
These typedefs include ones for each node type and node pointer type,
as well as special typedefs for "map"'s value type.
Although the associative containers already supported incomplete types, this
patch makes it official by adding tests.
This patch will be followed up shortly with various cleanups within __tree and
fixes for various map bugs and problems.

OpenMP 4.5 allows to privatize non-static data members of current class
in non-static member functions. Patch adds initial support for data
members.

This avoids unnecessarily passing them around when calling helper
functions. It may also be slightly faster to call clear() on the
datastructures instead of freshly initializing them for each block.

it to actually test the new pass manager AA wiring.
This patch was extracted from the (somewhat too large) D12357 and
rebosed on top of the slightly different design of the new pass manager
AA wiring that I just landed. With this we can start testing the AA in
a thorough way with the new pass manager.
Some minor cleanups to the code in the pass was necessitated here, but
otherwise it is a very minimal change.

Cleanuppads may be merged together if one is the only predecessor of the
other in which case a simple transform can be performed: replace the
a cleanupret with a branch and remove an unnecessary cleanuppad.

TLSADDR nodes are lowered into actuall calls inside MC. In order to prevent
shrink-wrapping from pushing prologue/epilogue past them (which result
in TLS variables being accessed before the stack frame is set up), we
put markers, so that the stack gets adjusted properly.
Thanks to Quentin Colombet for guidance/help on how to fix this problem!

Summary:
Instead of trying to replace SMRD instructions with a VGPR base pointer
with an equivalent MUBUF instruction, we now copy the base pointer to
SGPRs using v_readfirstlane.
This is safe to do, because any load selected as an SMRD instruction
has been proven to have a uniform base pointer, so each thread in the
wave will have the same pointer value in VGPRs.
This will fix some errors on VI from trying to replace SMRD instructions
with addr64-enabled MUBUF instructions that don't exist.

Summary:
This bug was originally fixed in http://reviews.llvm.org/D7201.
However it was broken again by the fix to https://llvm.org/bugs/show_bug.cgi?id=22605.
This patch re-fixes __wrap_iter with GCC by providing a forward declaration of <vector> before the friend declaration in __wrap_iter.
This patch avoids the issues in PR22605 by putting canonical forward declarations in <iosfwd> and including <iosfwd> in <vector>.
<iosfwd> was chosen as the canonical forward declaration headers for the following reasons:
1. `<iosfwd>` is small with almost no dependancies.
2. It already forward declares `std::allocator`
3. It is already included in `<iterator>` which we need to fix the GCC bug.
This patch fixes the test "gcc_workaround.pass.cpp"

Summary:
According to the C++ standard <stdbool.h> isn't allowed to define `true` `false` or `bool`. However these macros are sometimes defined by the compilers `stdbool.h`.
Clang defines the macros whenever `__STRICT_ANSI__` isn't defined (ie `-std=gnu++11`).
New GCC versions define the macros in C++03 mode only, older GCC versions (4.9 and before) always define the macros.
This patch adds a wrapper header for `stdbool.h` that undefs the required macros.

option. Previously these options could both be used to specify that you were
compiling the implementation file of a module, with a different set of minor
bugs in each case.
This change removes -fmodule-implementation-of, and instead tracks a flag to
determine whether we're currently building a module. -fmodule-name now behaves
the same way that -fmodule-implementation-of previously did.

Figured this would be a problem, but didn't want to jump the gun - large
inputs demonstrate it pretty easily (mostly for type units, but might as
well do the same for CUs too). A random sample 6m27s -> 27s change.
Also, by checking this up-front for CUs (rather than when building the
cu_index) we can probably provide better error messages (see FIXMEs),
hopefully providing the name of the CUs rather than just their
signature.

Summary:
When optimizing for size, sqrt calls can be incorrectly selected as
AVX512 VSQRT instructions. This is because X86InstrAVX512.td has a
`Requires<[OptForSize]>` in its `avx512_sqrt_scalar` multiclass
definition. Even if the target does not support AVX512, the class can
apparently still be chosen, leading to an incorrect selection of
`vsqrtss`.
In PR26625, this lead to an assertion: Reg >= X86::FP0 && Reg <=
X86::FP6 && "Expected FP register!", because the `vsqrtss` instruction
requires an XMM register, which is not available on i686 CPUs.
