ACPICA: iASL: Enhance detection of non-ascii or corrupted input files.
ACPICA commit 08170904011f1e8f817d9e3a9f2bb2438aeacf60
For the compiler part (not disassembler).
- Characters not within a comment must be be ASCII (0-0x7F), and
now either printable or a "space" character.
Provides better detection of files that cannot be compiled.
This patch only affects iASL which is not in the Linux upstream.
