Reject encodings determined at runtime as source code encodings 
The encodings determined at runtime are affected by the runtime
environment, such as the OS and locale, while the file contents are
not.

02d8bad6e1 Fix memory leak in parser for invalid syntax 
The strterm is leaked when there is invalid syntax.

For example:

    10.times do
      100_000.times do
        begin
          RubyVM::InstructionSequence.compile('private def foo = puts "Hello"')
        rescue SyntaxError
        end
      end

      puts `ps -o rss= -p #{$$}`
    end

db476cc71c Introduce NODE_SYM to manage symbol literal 
`:sym` was managed by `NODE_LIT` with `Symbol` object.
This commit introduces `NODE_SYM` so that

1. Symbol literal is detectable from AST Node

41e2d180a3 Do not convert NODE_STR to NODE_LIT when the string is hash key 
parse.y converted NODE_STR when the string is hash key like

```
h1 = {"str1" => 1}
m1("str2" => 2)
m2({"str3" => 3})
```

This commit stop the conversion.
`static_literal_node_p` needs to know the node is for hash key or not
for the optimization.

83c98ead4e Do not remove hash duplicated keys in parse.y 
When hash keys are duplicated, e.g. `h = {k: 1, l: 2, k: 3}`,
parser changes node structure for correct compilation.
This generates tricky AST. This commit removes AST manipulation
from parser to keep AST structure simple.

51149f335e Keep unused literal nodes 
For static analysis, it’s better to keep unused literal nodes.
If simply change `block_append` to fall through, both "unused literal ignored"
and "possibly useless use of a literal in void context" warnings
are shown for the same line. But it’s verbose then remove
"unused literal ignored" warning.

This kind of optimization is already implemented on compile.c.
`compile_block` calls `iseq_compile_each0` with `popped = 1` when NODE_BLOCK
has next.
