Pekka Jaaskelainen 2a1cc587bf [OpenCL] always use SPIR address spaces for kernel_arg_addr_space MD
It doesn't make sense to use the target's address space ids in this context as
this is metadata that should be referring to the "logical" OpenCL address spaces.
For flat AS machines like all "CPUs" in general, the logical AS info gets lost as
there's only one address space (0).

This commit changes the logic such that we always use the SPIR address space
ids for the argument metadata. It thus allows implementing the clGetKernelArgInfo()
and the other detection needs.

Neil Hickey f603672b5c Improve handling of floating point literals in OpenCL to only use double precision if the target supports fp64.
This change makes sure single-precision floating point types are used if the 
cl_fp64 extension is not supported by the target.

Also removed the check to see whether the OpenCL version is >= 1.2, as this has
been incorporated into the extension setting code.

James Molloy 6df8f27c95 [InlineCost] Remove skew when calculating call costs
When calculating the cost of a call instruction we were applying a heuristic penalty as well as the cost of the instruction itself.

However, when calculating the benefit from inlining we weren't discounting the equivalent penalty for the call instruction that would be removed! This caused skew in the calculation and meant we wouldn't inline in the following, trivial case:

  int g() {
    h();
  }
  int f() {
    g();
  }

Pablo Barrio 7ce2c5ecaf [JumpThreading] Prevent non-deterministic use lists
Summary:
Unfolding selects was previously done with the help of a vector
of pointers that was then sorted to be able to remove duplicates.
As this sorting depends on the memory addresses, it was
non-deterministic. A SetVector is used now so that duplicates are
removed without the need of sorting first.

Eric Fiselier c79c9d8536 Add explicit (void) cast to unused unique_ptr::release() results
Summary:
This patch adds explicit `(void)` casts to discarded `release()` calls to suppress -Wunused-result.

This patch fixes *all* warnings are generated as a result of [applying `[[nodiscard]]`  within libc++](https://reviews.llvm.org/D26596).
Similar fixes were applied to Clang in r286796.

Saleem Abdulrasool d6da74f22b Demangle: only demangle mangled symbols
Only attempt to demangle symbols which have the itanium C++ prefix of `_Z`.
This ensures that we do not treat any symbol name as a managled named.  We would
previously treat a C function `f` as a mangled name and decode that to `float`
incorrectly.

While it is easy to add tests for this, Mehdi recommended against introducing
tests for the demangler as libc++abi should cover the testing.

Saleem Abdulrasool 4d7f90b064 __cxa_demangle: allow demangling invocation blocks
The block invocation function uses an extension where the prefix is ___Z
as opposed to _Z.  This should make the tests pass again.

Disable a negative test which was testing a crasher.  The symbol being
demangled is not a valid mangled symbol and will return a nullptr.

Adjust the type info decoding test to be a valid symbol name.

Eric Fiselier 28349f9bf2 Add check-cxx-abilist target when supported.
This patch adds a `check-cxx-abilist` target which verifies the libc++.so ABI
when the current build configuration matches the configuration used to generate
the ABI lists.

In order to make this change `HandleOutOfTreeLLVM.cmake` needed to be modified
to include `LLVMConfig.cmake` so that `TARGET_TRIPLE` is defined. Hopefully
the changes needed to accommodate this won't break existing build
configurations.

Saleem Abdulrasool f13ad10208 __cxa_demangle: ensure that we have a mangled symbol
Ensure that we have a mangled symbol before attempting to demangle it.  We would
previously treat any input as a mangled symbol rather than checking that the
symbol has the initial C++ Itanium v3 mangling prefix of `_Z`.  This changes the
behaviour from the previous case which would undecorate `f` to `float` rather
than nullptr as it should.

Unfortunately, we do not have any negative testing for the demangler.

Craig Topper b8596e4d1d [X86] Cleanup 'x' and 'y' mnemonic suffixes for vcvtpd2dq/vcvttpd2dq/vcvtpd2ps and similar instructions.
-Don't print the 'x' suffix for the 128-bit reg/mem VEX encoded instructions in Intel syntax. This is consistent with the EVEX versions.
-Don't print the 'y' suffix for the 256-bit reg/reg VEX encoded instructions in Intel or AT&T syntax. This is consistent with the EVEX versions.
-Allow the 'x' and 'y' suffixes to be used for the reg/mem forms when we're assembling using Intel syntax.
-Allow the 'x' and 'y' suffixes on the reg/reg EVEX encoded instructions in Intel or AT&T syntax. This is consistent with what VEX was already allowing.

This should fix at least some of PR28850.

`shl nsw i8 1, i8 8` is poison, but `mul i8 1, i8 128` is not.

This was discussed previously here:
http://lists.llvm.org/pipermail/llvm-dev/2015-April/084195.html.  From
the discussion, it was not clear which semantics we want for `shl`, but
for now at least make the language reference more accurate.

Tobias Grosser 5743e8de86 [SCEVAffinator] Do not scan redundantly for parameters
In r286430 "SCEVValidator: add new parameters resulting from constant
extraction" we added functionality to scan for parameters after constant
extraction has taken place to ensure newly created parameters are correctly
registered. This addition made the already existing registration of parameters
redundant. Hence, we remove the corresponding call in this commit.

An alternative solution would have been to also perform constant extraction when
validating SCEV expressions and to then scan for parameters when validating
a SCEV expression. However, as SCEV validation is used during SCoP detection
where we want to be especially fast, adding additional functionality on this
hot path should be avoided if good alternatives exist. In this case, we can
choose to continue to only transform SCEV expression when actually modeling
them. As all transformations we perform are expected to not change the validity
of the SCEV expressions, this solution seems preferable.
