The global names were created using a hash based on the address
of std::vector::data address. Since the memory may be reused
by different std::vector's, this may cause non-equivalent
constant expressions to map to the same name. This is what is happening
in the modified flang/test/Lower/constant-literal-mangling.f90 test.
I changed the name creation to use a map between the constant expressions
and corresponding unique names. The uniquing is done using a name counter
in FirConverter. The effect of this change is that the equivalent
constant expressions are now mapped to the same global, and the naming
is "stable" (i.e. it does not change from compilation to compilation).
Though, the issue is not HLFIR specific it was affecting several tests
when using HLFIR lowering.
