Suport for `ldc MethodType` and `ldc Dynamic` is missing

[Maccimo]

Method RawInstListBuilder::buildLdcInsnNode() is missing support for ldc with constant pool entries of type CONSTANT_MethodType or CONSTANT_Dynamic as an argument.
An attempt to load class file with above mentioned instructions will fail with "Unknown LDC constant" exception.

The following gist can be used as a reproducer: https://gist.github.com/Maccimo/b760180649ec645827a058745d95b749
It contains both compiled class and asmtools jasm source for class file.
