Optimize static constructor calls/checks

[drcjt]

Currently any of the triggers listed in ECMA 335 I.8.9.5 will cause the compiler to insert a call to the static constructor.
The code for the static constructor will self modify when running to replace itself with a single return instruction so subsequent calls to it will do nothing.

There is definitely room for improvement in terms of reducing the number of calls to the static constructors.
A method that performs two static field accesses to the same class with a static constructor will end up calling the static constructor twice. Would be good to try and implement some of these unnecessary calls

Consider recording details of static constructors called in a basic block and only add new calls if there isn't already a call being made

Maybe take inspiration from similar work in real dotnet runtime here -> dotnet/runtime#64242
