Ulrich Weigand 48b40834dc [SystemZ] Support z15 processor name
The recently announced IBM z15 processor implements the architecture
already supported as "arch13" in LLVM.  This patch adds support for
"z15" as an alternate architecture name for arch13.

Corrsponding LLVM support was committed as rev. 372435.

Richard Smith c624510f13 For PR17164: split -fno-lax-vector-conversion into three different
levels:

 -- none: no lax vector conversions [new GCC default]
 -- integer: only conversions between integer vectors [old GCC default]
 -- all: all conversions between same-size vectors [Clang default]

For now, Clang still defaults to "all" mode, but per my proposal on
cfe-dev (2019-04-10) the default will be changed to "integer" as soon as
that doesn't break lots of testcases. (Eventually I'd like to change the
default to "none" to match GCC and general sanity.)

Following GCC's behavior, the driver flag -flax-vector-conversions is
translated to -flax-vector-conversions=integer.

This reinstates r371805, reverted in r371813, with an additional fix for
lldb.

This breaks the LLDB build. I tried reaching out to Richard, but haven't
gotten a reply yet.

Ulrich Weigand b98bf60ef7 [SystemZ] Add support for new cpu architecture - arch13
This patch series adds support for the next-generation arch13
CPU architecture to the SystemZ backend.

This includes:
- Basic support for the new processor and its features.
- Support for low-level builtins mapped to new LLVM intrinsics.
- New high-level intrinsics in vecintrin.h.
- Indicate support by defining  __VEC__ == 10303.

Note: No currently available Z system supports the arch13
architecture.  Once new systems become available, the
official system name will be added as supported -march name.
