[CMake] Cleaning up some CMake warnings

BOOTSTRAP_DEFAULT_PASSTHROUGH shouldn't be passed, so it is renamed to _BOOTSTRAP_DEFAULT_PASSTHROUGH, to prevent passthrough.

CLANG_STAGE should be passed, so I've changed the code to log it if it is set outside the if(CLANG_ENABLE_BOOTSTRAP) block. This makes the variable always used, so the warning goes away.

Pre-instrumentation inline (pre-inliner) greatly improves the IR
instrumentation code performance, among other benefits. One issue of the
pre-inliner is it can introduce CFG-mismatch for COMDAT functions. This
is due to the fact that the same COMDAT function may have different early
inline decisions across different modules -- that means different copies
of COMDAT functions will have different CFG checksum.

In this patch, we propose a partially renaming the COMDAT group and its
member function/variable so we have different profile counter for each
version. We will post-fix the COMDAT function and the group name with its

Jordan Rose [Mon, 25 Jul 2016 18:34:51 +0000 (18:34 +0000)]
StringSwitch cannot be copied (take 2).

This prevents StringSwitch from being used with 'auto', which is
important because the inferred type is StringSwitch rather than the
result type. This is a problem because StringSwitch stores addresses
of temporary values rather than copying or moving the value into its
own storage.

This is a compromise that still allows wrapping StringSwitch in other
temporary structures, which (unlike StringSwitch) may be non-trivial
to set up and therefore want to at least be movable. (For an example,
