A large majority of the LIT tests of the clang static analyzer use RUN lines with the placeholder `%clang_analyze_cc1` which expands to `%clang_cc1 -analyze -setup-static-analyzer` where the only effect of `-setup-static-analyzer` is that it ensures that the macro `__clang_analyzer__` is defined. However, there were some tests that used `%clang_cc1 -analyze` directly; this commit changes those to using `%clang_analyze_cc1` for the sake of consistency. Previously `%clang_analyze_cc1` did not work within the directory `exploded-graph-rewriter` (because that directory has its own custom `lit.local.cfg`) but this problem was eliminated by the recent commit 40cc4379cda6e0d6efe72c55d1968f9cf427a16a, so it was possible to resolve and delete the FIXME comments asking for this change. There are a few tests that use `%clang --analyze` or other command-line flags (e.g. help flags), those are not affected by this change. This cleanup was discussed in the discourse thread https://discourse.llvm.org/t/taking-ownership-of-clang-test-analysis/84689/11
