  [profile] Use fprofile-continuous in compiler-rt tests (#126617)

PR #124353 introduced the clang option `-fprofile-continuous` to enable
continuous mode. Use this option in all compiler-rt tests, where applicable.

Changes can be summarized as follows:
1) tests that use `-fprofile-instr-generate` (`%clang_profgen`), which
is an option that takes profile file name, are changed like so:
```
-// RUN: %clang_profgen_cont <SOME-OPTIONS> -o %t.exe %s
-// RUN: env LLVM_PROFILE_FILE="%c%t.profraw" %run %t.exe
+// RUN: %clang_profgen=%t.profraw -fprofile-continuous <SOME-OPTIONS> -o %t.exe %s
+// RUN: %run %t.exe
```
2) tests that use `-fprofile-generate` (`%clang_pgogen`), which is an
option that takes a profile directory, are on case-by-case basis. Where
the default name "default_%m.profraw" works, those tests were changed to
use `%clang_pgogen=<dir>`, and the rest (`set-filename.c` and
`get-filename.c`) continued to use the `LLVM_PROFILE_FILE` environment
variable .
3) `set-file-object.c` uses different filename for different run of the
same executable, so it continued to use the `LLVM_PROFILE_FILE`
environment variable.
4) `pid-substitution.c` add a clang_profgen variation.
