Summary:
 The specification of the @llvm.memcpy.element.unordered.atomic intrinsic requires
that the pointer arguments have alignments of at least the element size. The existing
IRBuilder interface to create a call to this intrinsic does not allow for providing
the alignment of these pointer args. Having an interface that makes it easy to
construct invalid intrinsic calls doesn't seem sensible, so this patch simply
adds the requirement that one provide the argument alignments when using IRBuilder
to create atomic memcpy calls.

Summary:
This adds logic to CVP to remove some overflow checks.  It uses LVI to remove
operations with at least one constant.  Specifically, this can remove many
overflow intrinsics immediately following an overflow check in the source code,
such as:

if (x < INT_MAX)
    ... x + 1 ...

Summary:
`getauxval` was introduced in 18 & 21 depending on the architecture. Bump the
requirement to 21.

It also turns out that the NDK is finicky: NDK r13b doesn't include sys/auxv.h
when creating a standalone toolchain at API level 19 for ARM. So 18 didn't work
well with older NDKs.

This patch adds the ability to include the member function declarations
in the instruction selector class separately from the member bodies.

Defining GET_DAGISEL_DECL macro to any value will only include the member
declarations. To include bodies, define GET_DAGISEL_BODY macro to be the
selector class name. Example:

  class FooDAGToDAGISel : public SelectionDAGISel {
    // Pull in declarations only.
    #define GET_DAGISEL_DECL
    #include "FooISelDAGToDAG.inc"
  };

  // Include the function bodies (with names qualified with the provided
  // class name).
  #define GET_DAGISEL_BODY FooDAGToDAGISel
  #include "FooISelDAGToDAG.inc"

When neither of the two macros are defined, the function bodies are emitted
inline (in the same way as before this patch).

Summary:
This eliminates the boilerplate implementation of the iterator interface in
mapped_iterator.

This patch also adds unit tests that verify that the mapped function is applied
by operator* and operator->, and that references returned by the map function
are returned via operator*.

Patch by Igor Sugak. Thank you.

llvm-svn: 317901

Summary:
I want to leverage this to clean up some of the code in clang. This will allow us to simplify D39521 which was trying to do some of the same.

If we accurately keep the code in Host.cpp synced with new CPUs added to compile-rt/libgcc we should be able to use this file as a proxy for what's implemented in the libraries.

The entries for the CPUs recognized by the libraries use separate macros that define additional parameters like the name for __builtin_cpu_is and an alias string for the couple cases where __builtin_cpu_is accepts two different names.

All of the macros contain an ARCHNAME that is usually the same as the __builtin_cpu_is string, but sometimes isn't. This represents the name recognized by X86.td and -march.

I'm following the precedent set by ARM and AArch64 and adding this information to lib/Support/TargetParser.cpp

Summary:
LTO/Caching.cpp uses file rename to atomically set the value for a
cache key. On Windows, this fails when the destination file already
exists. Previously, LLVM would report_fatal_error in such
cases. However, because the old and the new value for the cache key
are supposed to be equivalent, it actually doesn't matter which one we
keep. This change makes it so that failing the rename when an openable
file with the desired name already exists causes us to report success
instead of fataling.

Rewrite the tests from using plain 'assert' mixed with some nosetests
methods to the standard unittest module layout. Improve the code
to use the most canonical assertion methods whenever possible.

This has a few major advantages:

- the code uses standard methods now, resulting in a reduced number
of WTFs whenever someone with basic Python knowledge gets to read it,

- completely unnecessary dependency on nosetests is removed since
the standard library supplies all that is necessary for the tests
to run,

- the tests can be run via any test runner, including the one built-in
in Python,

- the failure output for most of the tests is improved from 'assertion
x == y failed' to actually telling the values.

Change the test format for SVE assembler/disassembler tests to be less verbose and have both tests in the same file.

The tests check the following:

 * All instructions are assembled correctly into the right encoding.
 * All instructions are disassembled correctly (into the preferred assembly format)
 * Without -mattr=+sve the instructions are not assembled.
 * Without -mattr=+sve the instructions are not disassembled.

This patch also adds several negative tests for SVE add/sub.

Summary:
[OpenMP] diagnose assign to firstprivate const

Clang does not diagnose assignments to const variables declared
firstprivate.  Furthermore, codegen is broken such that, at run time,
such assignments simply have no effect.  For example, the following
prints 0 not 1:

int main() {
  const int i = 0;
  #pragma omp parallel firstprivate(i)
  { i=1; printf("%d\n", i); }
  return 0;
}

This commit makes these assignments a compile error, which is
consistent with other OpenMP compilers I've tried (pgcc 17.4-0, gcc
6.3.0).
