[ARM] Command-line options for embedded position-independent code
This patch (with the corresponding ARM backend patch) adds support for
some new relocation models:
* Read-only position independence (ROPI): Code and read-only data is accessed
PC-relative. The offsets between all code and RO data sections are known at
static link time.
* Read-write position independence (RWPI): Read-write data is accessed relative
to a static base register. The offsets between all writeable data sections
are known at static link time.
These two modes are independent (they specify how different objects
should be addressed), so they can be used individually or together.
These modes are intended for bare-metal systems or systems with small
real-time operating systems. They are designed to avoid the need for a
dynamic linker, the only initialisation required is setting the static
base register to an appropriate value for RWPI code.
There is one C construct not currently supported by these modes: global
variables initialised to the address of another global variable or
function, where that address is not known at static-link time. There are
a few possible ways to solve this:
* Disallow this, and require the user to write their own initialisation
function if they need variables like this.
* Emit dynamic initialisers for these variables in the compiler, called from
the .init_array section (as is currently done for C++ dynamic initialisers).
We have a patch to do this, described in my original RFC email
(http://lists.llvm.org/pipermail/llvm-dev/2015-December/093022.html), but the
feedback from that RFC thread was that this is not something that belongs in
clang.
* Use a small dynamic loader to fix up these variables, by adding the
difference between the load and execution address of the relevant section.
This would require linker co-operation to generate a table of addresses that
need fixing up.

These two modes are independent (they specify how different objects

Summary:
They are now lexed as a single token on targets where
MCAsmInfo::HasMipsExpressions is true and then parsed in a similar way to
the '~' operator as part of MCExpr::parseExpression.
As a result:
* expressions and immediates no longer have different parsing rules. The
difference is now solely down to whether evaluateAsAbsolute() succeeds.
* %hi(%neg(%gp_rel(x))) are no longer parsed as a single operator and
decomposed into the three MipsMCExpr nodes. They are parsed directly as
three MipsMCExpr nodes.
* parseMemOperand no longer needs to eat all the surrounding parenthesis
to get at the outermost operator to make this work
* %hi(%neg(%gp_rel(x))) and %lo(%neg(%gp_rel(x))) are no longer the only
3-in-1 relocs that parse for N64. They're still the only combinations that
are permitted in relocatable expressions though. Fixing that should be a
later patch.
* We no longer need to list all the tokens that can occur as the first token of
an expression or immediate.

This change also prevents the incorrect lowering of %lo(2*4)+foo to
%lo(8+foo) which is not an equivalent expression (the difference is
whether foo is truncated to 16-bit or not) and the test has been
updated to account for the macro expansion the correct expression requires.

AVX-512: Changed lowering of BITCAST between i1 vectors and i8/i16/i32 integer values
Optimized lowering of BITCAST node. The BITCAST node can be replaced with COPY_TO_REG instead of KMOV.
It allows to suppress two opposite BITCAST operations and avoid redundant "movs".

[Coroutines] Part 5: Add CGSCC restart trigger
Summary:
CoroSplit pass processes the coroutine twice. First, it lets it go through
complete IPO optimization pipeline as a single function. It forces restart
of the pipeline by inserting an indirect call to an empty function "coro.devirt.trigger"
which is devirtualized by CoroElide pass that triggers a restart of the pipeline by CGPassManager.
(In later patches, when CoroSplit pass sees the same coroutine the second time, it splits it up,
adds coroutine subfunctions to the SCC to be processed by IPO pipeline.)
Documentation and overview is here: http://llvm.org/docs/Coroutines.html.
Upstreaming sequence (rough plan)
1.Add documentation. (https://reviews.llvm.org/D22603)
2.Add coroutine intrinsics. (https://reviews.llvm.org/D22659)
3.Add empty coroutine passes. (https://reviews.llvm.org/D22847)
4.Add coroutine devirtualization + tests.
ab) Lower coro.resume and coro.destroy (https://reviews.llvm.org/D22998)
c) Do devirtualization (https://reviews.llvm.org/D23229)
5.Add CGSCC restart trigger + tests. <= we are here
6.Add coroutine heap elision + tests.
7.Add the rest of the logic (split into more patches)

Headers: Add ARM support to intrin.h for MSVC compatibility
This fixes compiling with headers from the Windows SDK for ARM, where the
YieldProcessor function (in winnt.h) refers to _ARM_BARRIER_ISHST.
The actual MSVC armintr.h contains a lot more definitions, but this is enough to
build code that uses the Windows SDK but doesn't use ARM intrinsics directly.
An alternative would to just keep the addition to intrin.h (to include
armintr.h), but not actually ship armintr.h, instead having clang's intrin.h
include armintr.h from MSVC's include directory. (That one works fine with
clang, at least for building code that uses the Windows SDK.)
