Summary: Add file/line information to backtraces

Bugs Fixed:
LPP-4549 'runtime warnings should include file references, line #s'

Technical Reviewer: max, dda at ddanderson.com (pending)
QA Reviewer: ewinard (pending)

Details:
     LzMessage: Get file/line information from backtrace if available,
     tweak format of locationString.

     LzDebug.*: correct padding computation for computeSlotDescription.

     LzDebug.js: _dbg_name takes precedence over runtime function name.

     LzBacktrace, LzRuntime: Move backtraceStack creation to runtime  
so it is
     available as early as needed.

     LzBacktrace:  Add __LzStackFrame.isUserFrame,
     .filename, .lineno.  Update _dbg_name to display file and line
     information.  Add LzBacktrace.userStackFrame to get first non-LFC
     frame from a backtrace.

     Compiler: Correct precedence computations for unparser, ensure
     parens are added in all the appropriate places.  Needed to handle
     expression-lists that backtrace annotation inserts.

     JavascriptGenerator, CodeGenerator: Copy location info when
     re-writing functions.  Note line numbers of call sites for
     backtrace.  Note file and line on functions for backtraces.

Tests:
     smokecheck with backtrace on shows file/line information in debug
     messages and in backtraces.
