When loading a value of a static final field with trivial initializer
generate a Constant instruction instead of LoadStaticField.
Initializer of a static field is considered trivial if it is null, int,
double, String or bool literal.

This instruction is essentially just a StaticCall to a fixed
target. Make this explicit by actually using StaticCall to
represent it.

The Incremental Kernel Compiler (IKG) will produce kernel files without
metadata.
Right now the VM will make all closure calls dynamic calls if the
call-site attribute metadata is not present. This causes closure code
to run significantly slower due to dyn:call forwarders and the type
checks it will perform.
This change takes - in addition to the metadata - the new
FunctionInvocation.kind into account - which also tells us whether a
function invocation is based on a real function type.

Front-end marks certain calls (currently in collection literals) as
not requiring covariant parameter checks (invariant).
VM can use that flag to generate calls through unchecked entry point.
