This commit back-ports the implementations of IsRename() and MayAlias()
from the upstream 8.0 branch wholesale. Fixes several bugs where V8's
load elimination pass considered values to be alive when they weren't.

Adds `napi_set_instance_data()` and `napi_get_instance_data()`, which
allow native addons to store their data on and retrieve their data from
`napi_env`. `napi_set_instance_data()` accepts a finalizer which is
called when the `node::Environment()` is destroyed.

This entails rendering the `napi_env` local to each add-on.

This is a security release.

Vulnerabilities fixed:
* **CVE-2019-15606**:
          HTTP header values do not have trailing OWS trimmed.
* **CVE-2019-15605**:
          HTTP request smuggling using malformed Transfer-Encoding header.
* **CVE-2019-15604**:
          Remotely trigger an assertion on a TLS server with a malformed
          certificate string.

Also, HTTP parsing is more strict to be more secure. Since this may
cause problems in interoperability with some non-conformant HTTP
implementations, it is possible to disable the strict checks with the
`--insecure-http-parser` command line flag, or the `insecureHTTPParser`
http option. Using the insecure HTTP parser should be avoided.

HTTP header values can have trailing OWS, but it should be stripped.  It
is not semantically part of the header's value, and if treated as part
of the value, it can cause spurious inequality between expected and
actual header values.

Note that a single SPC of leading OWS is common before the field-value,
and it is already handled by the HTTP parser by stripping all leading
OWS. It is only the trailing OWS that must be stripped by the parser
user.

MAX_HWM was added in 9208c890 where the highwatermark was changed to
always increase in steps of highest power of 2 to prevent increasing
hwm excessivly in tiny amounts.

Why a limit was added on the highwatermark is unclear but breaks
existing usage where a larger read size is used. The invariant for
read(n) is that a buffer of size n is always returned. Considering
a maximum ceiling on the buffer size breaks this invariant.

This PR significantly increases the limit to make it less likely to
break the previous invariant and also documents the limit.

Allow use of <code> in header elements without styling side effects. We
can add styling later if desired. The goal here is to allow code to be
set off in markdown without needing to escape characters and do lint
exceptions for terms. This is probably a win in terms of accessibility
too although it would be moreso if we had some visual differentiation
for <code> inside of headers. As mentioned above, that can always be
added at a later time.

The ability to pause input processing was added in 8a4a1931 but
introduced a session memory accounting mismatch leading to potential
NGHTTP2_ENHANCE_YOUR_CALM errors.

After pausing
(https://github.com/nodejs/node/blob/f36331c1bfa4c4c202346b05dc3bd672f653e4df/src/node_http2.cc#L871),
the early return on line 873 skips the
DecrementCurrentSessionMemory(stream_buf_.len) call below (line 878).

When we later finished processing the input chunk
(https://github.com/nodejs/node/blob/f36331c1bfa4c4c202346b05dc3bd672f653e4df/src/node_http2.cc#L1858),
we were calling DecrementCurrentSessionMemory(stream_buf_offset_) [line
1875] which was a no-op since we just set stream_buf_offset_ to 0 [line
1873].

The correct amount to decrement by is still stream_buf_.len, since
that's the amount we skipped previously (line 878).
