IlSpy mistakenly assumes some `out` variables are already in scope

[nikitalita]

When decompiling a statement that contains an out variable, ILSpy will check to see if that particular named variable is in already scope before determining whether or not to also make it a declaration. However, it sometimes incorrectly determines that some out vars are already in scope when they actually aren't, such as the following example:

This tends to only crop up if we're using a pdb containing the debug names of the variables (we would otherwise just choose unique names for each out variable)
