Added argv array check/allocation for parallel directly nested inside the teams
construct, as new coming Fortran codegen passes parameters directly into
kmpc_fork_call missing same parameters in kmpc_fork_teams (earlier codegen
passed to parallel the subset of parameter passed to teams, and thus
no check/allocation needed).

Patch updates the version script parser to parse versioned files.
In a simple way, just adding them to VersionScriptGlobals list.

This allows better catching of compiler errors since we can use
the override keyword to verify that methods are actually
overridden.
Also in this patch I've changed from storing a boolean Error
code everywhere to returning an llvm::Error, to propagate richer
error information up the call stack.

Daniel Berlin expressed some real concerns about the port and proposed
and alternative approach. I'll revert this for now while working on a
new patch, which I hope to put up for review shortly. Sorry for the churn.

When calculating a square root using Newton-Raphson with two constants,
a naive implementation is to use five multiplications (four muls to calculate
reciprocal square root and another one to calculate the square root itself).
However, after some reassociation and CSE the same result can be obtained
with only four multiplications. Unfortunately, there's no reliable way to do
such a reassociation in the back-end. So, the patch modifies NR code itself
so that it directly builds optimal code for SQRT and doesn't rely on any
further reassociation.

This is currently only performed in the Vectorizer. I will change this
as symbolic stride collection is moved to LAA.
This test will track when the actual functional change occurs.

This patch allows LLDB for AArch64 to watch all bytes, words or double words individually on non 8-byte alligned addresses.
This patch also adds tests to verify this functionality.

PltZero (or PLT[0]) was an appropriate name for the little code
we have at beginning of the PLT section when we only supported x86
since the code for x86 just fits in the first PLT slot.
It's not the case anymore. The code for ARM64 occupies first two
slots, so PltZero spans PLT[0] and PLT[1], for example.
This patch renames it to avoid confusion.

This fixes IMAGE_REL_I386_DIR32, IMAGE_REL_I386_DIR32NB,
IMAGE_REL_I386_SECREL, and IMAGE_REL_I386_REL32 relocations.

For ARM and MIPS, we don't need to call this function.
This patch passes a symbol instead of a PLT entry address
so that the target handler can call it if necessary.

The R_ARM_PLT32 relocation is deprecated and is not produced by MC.
This means that the code being deleted is dead from the .o point of
view and was making the .s more confusing.

The -mattr options in these four tests have no effect on the output of
llvm-objdump. In the case of the two Mips tests, removing the -mattr option
left duplicate RUN lines so the duplicates have been removed.

Summary:
This patch fixes an issue detected when firstprivate variables are passed to an OpenMP outlined function vararg list. Currently they are not compatible with what the runtime library expects causing malfunction in some targets.
This patch fixes the issue by moving the casting logic already in place for offloading to the common code that creates the outline function and arguments and updates the regression tests accordingly.

Both parameters to visitTypeBegin are actually members of CVRecord,
so we can just pass CVRecord instead of destructuring it.

Summary:
Conceptually, this is very close to the existing functionality of misc-move-const-arg, which is why I'm adding it here and not creating a new check. For example, for a type A that is both movable and copyable, this
const A a1;
A a2(std::move(a1));
is not only a case where a const argument is being passed to std::move(), but the result of std::move() is also being passed as a const reference (due to overload resolution).
The new check typically triggers (exclusively) in cases where people think they're dealing with a movable type, but in fact the type is not movable.
