Reland "[mlir][test] Fix IR/AttributeTest.cpp compilation on Solaris" 

The `IR/AttributeTest.cpp` test fails to compile on Solaris:
```

```
Because `char` is `signed` by default on Solaris and `int8_t` is
`char`. `std::is_same<int8_t, char>` is `true` unlike elsewhere, rejecting
the one-arg `allocate` overload.

Fixed by renaming the two overloads to avoid the ambiguity.

Tested on `amd64-pc-solaris2.11` ,`sparcv9-sun-solaris2.11`, and
`x86_64-pc-linux-gnu`.
