Fix issue with test that caused bildbot failure These tests did not specify the target. The failure was triggered by change - https://reviews.llvm.org/D33205 http://lab.llvm.org:8011/builders/clang-cmake-armv7-a15-full/builds/7314 which sets vector alignment to 8-byte for arm-targets (except for Android). So, fixing the test to make it target specific. llvm-svn: 304210

[OpenCL] Fix casting a true boolean to an integer vector. OpenCL v1.1 s6.2.2: for the boolean value true, every bit in the result vector should be set. This change treats the i1 value as signed for the purposes of performing the cast to integer, and therefore sign extend into the result.

[Bugfix] Fix ICE on constexpr vector splat. In {CG,}ExprConstant.cpp, we weren't treating vector splats properly. This patch makes us treat splats more properly. Additionally, this patch adds a new cast kind which allows a bool->int cast to result in -1 or 0, instead of 1 or 0 (for true and false, respectively), so we can sanely model OpenCL bool->int casts in the AST.

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.*}} `, (variable/constant/alias) `= ` with `={{.*}} `, or inserts appropriate `{{.*}} `.
