Update headers for Mac OS X installation to pick up 3.9+ headers

[hhellyer]

Xcode recently updated lldb on my system. Now lldb reports:
$ lldb -v
lldb-370.0.40
Swift-3.1

However this doesn't match up to the actual lldb levels so I forced the installation script to use 3.9 headers. This built and as a result I was able to run v8 findjsobjects without needing to run one of the scripts to generate memory regions.

This simplifies the usage of llnode a lot so I will update the npm install scripts. Ideally I need to find a table that maps Xcode versions to 'real' lldb releases from the lldb git repository.

Hooray!

See: Homebrew/homebrew-core#12608 . Will close this once it lands.

Thanks for update!

I'll push a fix in the npm build script as well.

For reference I asked about keeping track of the lldb levels in Xcode - the response was that newer levels of lldb should be compatible with older headers. We only need to update the headers if there is a feature we need. (Which there is in this case.)

I've pushed an update to the npm script. Once this is landed I'll need to update the npm again so that Mac users installing via npm get the benefit.

v1.4.3 has been published:

I can build the plugin with npm install llnode and run findjsobjects without creating a memory ranges file on MacOS X. Closing this now.
