This\r\nsolution is known to have limitations, especially w.r.t. scaling to\r\nsupport all OpenCL builtin functions, yet it is trivial and seemed\r\nsufficient for this prototype. It should nonetheless be replaced with a\r\ngeneric solution later on.\r\n\r\nAdd two new test cases, covering the SPIR-V generation. Extend an\r\nexisting test case, covering the case where multiple overloads of the\r\nsame builtin function are used in the same program.\r\n\r\nSigned-off-by: Marco Antognini \u003cmarco.antognini@arm.com\u003e\r\n\r\n* Improve lowering of builtin functions\r\n\r\nRely on clspv::Builtins instead of a manual mapping of mangled names to\r\nlower builtin functions in order to ensure the design can scale to\r\nsupport all OpenCL builtin functions.\r\n\r\nAdd new testcase to illustrate the flexibility of the new approach.\r\n\r\nSigned-off-by: Marco Antognini \u003cmarco.antognini@arm.com\u003e"

This is effectively\r\nequivalent to using the linker option --whole-archive for static build,\r\nbut in a more portable way as not all toolchains support this option.\r\n\r\nPreviously, the output of `clspv-opt --help-hidden` and `clspv\r\n--help-hidden` would differ from a shared library build to a static\r\nlibrary build. There are still some differences but they seem to be\r\nunrelated to clspv passes but rather related to LLVM passes.\r\n\r\nThe MultiVersionUBOFunctionsPass pass is using such a global static\r\nobject. Update existing test to cover this pass.\r\n\r\nBump required CMake version. Chose 3.13.4 as it is required by the\r\nlatest LLVM and it supports linking against OBJECT libraries.\r\n\r\nAdd a missing dependency of clspv_passes that was identified by using\r\nOBJECT library when using a shared build.\r\n\r\nSigned-off-by: Marco Antognini \u003cmarco.antognini@arm.com\u003e"
