[Clang][Driver] Split fsanitize.c test
The fsanitize.c test is one of the slowest tests we have: ``` -- Testing: 1 tests, 1 workers -- PASS: Clang :: Driver/fsanitize.c (1 of 1) Testing Time: 18.42s ``` It has become the single monolithic test for almost all -fsanitize= options. Given its current size, it makes sense to split it up into smaller focused tests to allow for better parallelization but also help the FileCheck tool by reducing number of lines to check. The new test time with parallelization on my machine is: ``` -- Testing: 16 tests, 16 workers -- PASS: Clang :: Driver/fsanitize-numerical.c (1 of 16) PASS: Clang :: Driver/fsanitize-safe-stack.c (2 of 16) PASS: Clang :: Driver/fsanitize-memtag.c (3 of 16) PASS: Clang :: Driver/fsanitize-realtime.c (4 of 16) PASS: Clang :: Driver/fsanitize-baremetal.c (5 of 16) PASS: Clang :: Driver/fsanitize-scudo.c (6 of 16) PASS: Clang :: Driver/fsanitize-trap.c (7 of 16) PASS: Clang :: Driver/fsanitize-leak.c (8 of 16) PASS: Clang :: Driver/fsanitize-recover.c (9 of 16) PASS: Clang :: Driver/fsanitize-skip-hot-cutoff.c (10 of 16) PASS: Clang :: Driver/fsanitize-minimal-runtime.c (11 of 16) PASS: Clang :: Driver/fsanitize-cfi.c (12 of 16) PASS: Clang :: Driver/fsanitize-merge.c (13 of 16) PASS: Clang :: Driver/fsanitize-annotate-debug-info.c (14 of 16) PASS: Clang :: Driver/fsanitize-undefined.c (15 of 16) PASS: Clang :: Driver/fsanitize.c (16 of 16) Testing Time: 7.10s ``` The original Driver/fsanitize.c test remains for tests where it is unclear that a single feature is being tested in isolation.
