c680eeab30 [IRBuilder][RS4GC] Require FunctionCallee when creating statepoint
This makes the statepoint methods in IRBuilder accept a
FunctionCallee, which carries both the callee and function type.
This is used to add the elementtype attribute to the statepoint call.

RS4GC requires an additional tweak to actually preserve that attribute
-- previously the attributes on the call were completely overwritten.

88024a724c [RS4GC] Use one DVCache for both inlineGetBaseAndOffset() and insertParsePoints()
This new test demonstrates a case where a base ptr is generated
twice for the same value: the first one is generated while
the gc.get.pointer.base() is inlined, the second is generated
for the statepoint. This happens because the methods
inlineGetBaseAndOffset() and insertParsePoints() do not share
their defining value cache used by the findBasePointer() method.
