b2cd98a98f C++: Confirm correct behaviour on C++20
Making `constexpr` imply `const` was correct for C++11 and was a correct
emulation of a GCC bug on GCC < 5.0. This test confirms that the problem
isn't there in C++20.

cd8e9a1ece C++: Demonstrate that constexpr implies const
This test shows that a member function declared `constexpr` also gets a
`const` specifier.

fe72b559d3 C++: Range analysis for unsigned AssignMulExpr
This is essentially a copy-paste job of `AssignAddExpr`, together with
the math from the `UnsignedMulExpr` support.

f90d779122 C++: Fix SimpleRangeAnalysis for AssignOperation
The range analysis wasn't producing useful bounds for `AssignOperation`s
(`+=`, `-=`) unless their RHS involved a variable. This is because a
shortcut was made in the `analyzableDef` predicate, which used to
specify that an analyzable definition was one for which we'd specified
the dependencies. But we can't distinguish between having _no
dependencies_ and having _no specification of the dependencies_.

The fix is to be more explicit about which definitions are analyzable.
To avoid too much repetition I'm still calling out to `analyzableExpr`
in the new code.
