I stared at `false /*declaration*/` for quite some time before giving up
and checking the actual function to see what it meant. Replacing with
`/* isDefinition = */ false` to save myself effort later.

Error out if -mfloat-abi=hard or -mhard-float is specified on the command
line and the target ABI is APCS. Previously clang issued no warnings or
errors and just passed the option to the backend, which had no effect on
code generation for targets using APCS.
This commit corrects the patch commited in r245866, which didn't take into
account the fact that not all darwin targets use APCS.

and CompilerInvocation::getFileSystemOpts by renaming it to getFileSystemOpts,
marking the const-returning access method const and adding a non-const version,
making the function prototypes identical to CompilerInstance::getFileSystemOpts.

We tried to provide a very nice diagnostic when diagnosing an assignment
to a const int & produced by a function call. However, we cannot always
determine what function was called.
This fixes PR24568.

Summary:
- Store the exception specification range's begin and end SourceLocation in DeclaratorChuck::FunctionTypeInfo. These SourceLocations can be used in a FixItHint Range.
- Add diagnostic; function concept having an exception specification.

We agreed for r245605 that, as long as we don't affect -O0 codegen
too much, it's OK to use native constructs rather than intrinsics.
Let's test that, starting with AVX2 here.
See PR24580.

As discussed in PR23648 - the intrinsics _m_from_int, _m_to_int and _m_prefetch are defined in mmintrin.h and prfchwintrin.h so we don't need to in Intrin.h
Added tests for _m_from_int and _m_to_int
D11338 already added a test for _m_prefetch

GNU attributes can have a leading and trailing __ appended/prepended to
the attribute name. While the parser and AttributeList::getKind did the
right thing, AttributeList::getAttributeSpellingListIndex did not.
This fixes PR24565.

Eventually, we will need sample profiles to be incorporated into the
inliner's cost models. To do this, we need the sample profile pass to
be a module pass.
This patch makes no functional changes beyond the mechanical adjustments
needed to run SampleProfile as a module pass.

Adds parsing/sema analysis/serialization/deserialization for array sections in OpenMP constructs (introduced in OpenMP 4.0).
Currently it is allowed to use array sections only in OpenMP clauses that accepts list of expressions.

This involved specializing handleUserFeatures so that we could perform
diagnostics on -only- user supplied features and migrating the rest of
the initialization functions to set features based on enabling and disabling
full feature sets. No functional change intended.

_rotl, _rotwl and _lrotl (and their right-shift counterparts) are official x86
intrinsics, and should be supported regardless of environment. This is in contrast
to _rotl8, _rotl16, and _rotl64 which are MS-specific.
Note that the MS documentation for _lrotl is different from the Intel
documentation. Intel explicitly documents it as a 64-bit rotate, while for MS,
since sizeof(unsigned long) for MSVC is always 4, a 32-bit rotate is implied.
