e.g. The locations of the NODE_BLOCK is fixed:
```

BEGIN {
:b
}
```
* Before
```
NODE_BLOCK (line: 5, code_range: (5,0)-(7,1))

* parse.y: Follow up of r61676. r61676 removed
ruby_sourceline from some actions. When stop to
use lineno of "n th" symbol, it's better to
use last location's lineno of "n-1 th" symbol.
e.g.
```
primary : k_begin {} bodystmt k_end
```
Before r61676 we use lineno of `@2` (ruby_sourceline).
In this case, last location's lineno of `k_begin` (`@1`)
is suitable.

We no longer need the compressed data once the inflate block is
called; so clear it ASAP to reduce memory overhead. This is a
small chunk, so it only saves a few hundred kilobytes with the

This change initializes nd_line, lineno of each node, by default, by
using the first line number of code range that bison tracks, instead of
extracting from lexer state.
The lexer state basically provides only the last line number of code
range, so many hacks are used to approximate the first line number. The
hacks have been introduced on demand, or very ad-hocly. I think this
change will make it possible to remove most of the hacks.

For garbage-concious users who use the `outbuf' argument of
`readpartial' to supply a destination buffer, this provides
a drastic reduction in garbage when inflating large inputs
in a streaming fashion.
This results in a anonymous RSS reduction in the reader
similar to the reduction in the writer from r61631.

yielded to Net::HTTPResponse#read_body methods. This
reduces malloc garbage (anonymous RSS) using the Linux-only

There's no need to allocate a temporary string when @rbuf is
empty, we can use it as the read_nonblock destination buffer to
save both allocation overhead and avoid a later memcpy.
This results in a halving user CPU time and tiny memory
reduction with the script below:

Not an encoding expert, but this seems necessary for the next
change. All of the IO#read, IO#read_nonblock and related
methods will return a binary string when given a length
argument; so anything appended to these buffers via <<
will be binary.
