Eliminate redundant bitwise operations when using a llvm/ADT/PointerUnion.
For comparison, with this code sample:
PointerUnion<int *, char *> Data;
PointerUnion<int *, char *> foo1() {
Data = new int;
return new int;
}
PointerUnion<int *, char *> foo2() {
Data = new char;
return new char;
}
Before this patch we would get:
define i64 @_Z4foo1v() uwtable ssp {
%1 = tail call noalias i8* @_Znwm(i64 4)
%2 = ptrtoint i8* %1 to i64
%3 = load i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%4 = and i64 %3, 1
%.masked.i = and i64 %2, -3
%5 = or i64 %4, %.masked.i
store i64 %5, i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%6 = tail call noalias i8* @_Znwm(i64 4)
%7 = ptrtoint i8* %6 to i64
%8 = and i64 %7, -3
ret i64 %8
}
define i64 @_Z4foo2v() uwtable ssp {
%1 = tail call noalias i8* @_Znwm(i64 1)
%2 = ptrtoint i8* %1 to i64
%3 = load i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%4 = and i64 %3, 1
%5 = or i64 %2, %4
%6 = or i64 %5, 2
store i64 %6, i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%7 = tail call noalias i8* @_Znwm(i64 1)
%8 = ptrtoint i8* %7 to i64
%9 = or i64 %8, 2
ret i64 %9
}
After the patch:
define i64 @_Z4foo1v() uwtable ssp {
%1 = tail call noalias i8* @_Znwm(i64 4)
%2 = ptrtoint i8* %1 to i64
store i64 %2, i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%3 = tail call noalias i8* @_Znwm(i64 4)
%4 = ptrtoint i8* %3 to i64
ret i64 %4
}
declare noalias i8* @_Znwm(i64)
define i64 @_Z4foo2v() uwtable ssp {
%1 = tail call noalias i8* @_Znwm(i64 1)
%2 = ptrtoint i8* %1 to i64
%3 = or i64 %2, 2
store i64 %3, i64* getelementptr inbounds (%"class.llvm::PointerUnion"* @Data, i64 0, i32 0, i32 0), align 8
%4 = tail call noalias i8* @_Znwm(i64 1)
%5 = ptrtoint i8* %4 to i64
%6 = or i64 %5, 2
ret i64 %6
}

PointerUnion::getAddrOf() does not need to be template since we can only
use the first pointer type for it. Rename it to getAddrOfPtr1().

Fix an obscure bug in PointerUnion that would bite PointerUnion3/4. Basically,
when checking isNull(), we'd pick off the sentinel bit for the outer
PointerUnion, but would not recursively convert the inner pointerunion to bool,
so if *its* sentinel bit is set, isNull() would incorrectly return false.
No testcase, because someone hit this when they were trying to refactor code
to use PointerUnion3, but they since found a better solution.

Add a simple type-safe bit-mangling pointer union class. This allows
you to do things like:
/// PointerUnion<int*, float*> P;
/// P = (int*)0;
/// printf("%d %d", P.is<int*>(), P.is<float*>()); // prints "1 0"
/// X = P.get<int*>(); // ok.
/// Y = P.get<float*>(); // runtime assertion failure.
/// Z = P.get<double*>(); // does not compile.
/// P = (float*)0;
/// Y = P.get<float*>(); // ok.
/// X = P.get<int*>(); // runtime assertion failure.
