poke: upgrade 4.1 -> 4.2

Changelog:
=============
* Bug fixes
  - Handle 'strdup' error correctly in mmap IO device.
  - Exclude unnamed fields when traversing struct types.  Fixes bug 31836.
  - Replace 'strtok' with 'strtok_r' in pkl-ast.
  - Fix the compiler to not accept invalid use of 'break'/'continue'
    statements.
  - Fix the compiler to emit the correct code for valid 'break'/'continue'
    statements in more unconventional cases.
  - Fix 'iogetb' to always produce a bit offset due to signature of
    'iobias' function.
  - Fix 'pkl_loc_to_source' to handle compilation from buffer correctly.
  - Fix use of 'assert' function in parser.
* Improvements
  - Diagnostics for invalid casts has been improved.
  - Improve diagnostics of '.ios' command.
* Build system update
  - Handle execution errors for 'pokefmt' tests.
* Pickles update
  - 'diff_structured' function in 'diff' pickle has been fixed to detect
    "simple types" correctly (types that have value semantics instead of
    reference semantics).
* Documentation update
  - Update reference manual to use '.vm disa' as short name for
    '.vm disassemble' instead of '.vm dis'.
* Internal changes
  - Internal machinery for compiler builtins has been removed.  These were
    no longer necessary.
* Jitter update
  - Update jitter submodule to incorporate a fix for 'configure' portability
    issue on some old systems.
