DebugInfoManager::AddDebugValueIfVarDeclIsVisible() adds
OpenCL.DebugInfo.100 DebugValue from DebugDeclare only when the
DebugDeclare is visible to the given scope. It helps us correctly
handle a reference variable e.g.,

{ // scope #1.
  int foo = /* init */;
  { // scope #2.
    int& bar = foo;
    ...

in the above code, we must not propagate DebugValue of int& bar for
store instructions in the scope #1 because it is alive only in
the scope #2.

We have an exception: If the given DebugDeclare is used for a function
parameter, DebugInfoManager::AddDebugValueIfVarDeclIsVisible() has
to always add DebugValue instruction regardless
of the scope. It is because the initializer (store instruction) for
the function parameter can be out of the function parameter's scope
(the function) in particular when the function was inlined.

Without this change, the function parameter value information always
disappears whenever we run the function inlining pass and
DebugInfoManager::AddDebugValueIfVarDeclIsVisible().

`DebugInfoManager::AddDebugValueIfVarDeclIsVisible()` adds
OpenCL.DebugInfo.100 DebugValue from DebugDeclare only when the
DebugDeclare is visible to the give scope. It helps us correctly
handle a reference variable e.g.,

{ // scope KhronosGroup#1.
  int foo = /* init */;
  { // scope KhronosGroup#2.
    int& bar = foo;
    ...

in the above code, we must not propagate DebugValue of `int& bar` for
store instructions in the scope KhronosGroup#1 because it is alive only in
the scope KhronosGroup#2.

We have an exception: If the given DebugDeclare is used for a function
parameter, `DebugInfoManager::AddDebugValueIfVarDeclIsVisible()` has

Can you surround the example with ``` (markdown)? Same with #1 and #2 -- otherwise they get misparsed by github.

Are the segfaults with the two windows CI bots unrelated to this change?

Not very familiar with this code, but looks okay to me. Thanks for the fix @jaebaek!

Thank you for the code review. In terms of the CI bot failures, I think it is related to the googletest updates. I believe #3922 temporarily fixes it. Let me rebase it and submit it.
