Subject: [PATCH] clover: fix memory leak related to optimize

Indeed, the object returned by LLVMCreatePassBuilderOptions()
was not freed.

For instance, this issue is triggered with "piglit/bin/cl-api-build-program":
Direct leak of 32 byte(s) in 1 object(s) allocated from:
    #0 0x7f6b15abdf57 in operator new(unsigned long) (/usr/lib64/libasan.so.6+0xb2f57)
    #1 0x7f6afff6529e in LLVMCreatePassBuilderOptions llvm-18.1.5/lib/Passes/PassBuilderBindings.cpp:83
    #2 0x7f6b1186ee41 in optimize ../src/gallium/frontends/clover/llvm/invocation.cpp:521
    #3 0x7f6b1186ee41 in clover::llvm::link_program(std::vector<clover::binary, std::allocator<clover::binary> > const&, clover::device const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >&) ../src/gallium/frontends/clover/llvm/invocation.cpp:554
    #4 0x7f6b1150ce67 in link_program ../src/gallium/frontends/clover/core/compiler.hpp:78
    #5 0x7f6b1150ce67 in clover::program::link(clover::ref_vector<clover::device> const&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, clover::ref_vector<clover::program> const&) ../src/gallium/frontends/clover/core/program.cpp:78
    #6 0x7f6b11401a2b in clBuildProgram ../src/gallium/frontends/clover/api/program.cpp:283
