Evgenii Kudriashov c5abcb0521 [X86][GlobalISel] Reorganize tests for G_PHI and support fp80 (#100047) ...

* Verified scalar support of G_PHI
* Added cases with i1, ptr and x86_fp80 types
* Added phi inputs variability

We don't enable tests for i686 due to lack of float/integer types in
legalizer. We don't distinguish between illegal 64 bit integer G_LOAD
and legal double load using X87. It leads to artificial G_MERGE_VALUES
of floats into a single double.
