411f911b60 Bump sym file version and add a couple sanity checks.
Bumping the version forces regeneration of any sym files created by old ORCA/C versions with the bug that was just fixed.

A couple sanity checks are also introduced when reading sym files, including one that would have caught that bug.

dc1b0aa29f Add lint flag to check for several forms of undefined behavior in computations.
This adds lint bit 5 (a value of 32), which currently enables checking for the following conditions:

*Integer overflow from arithmetic in constant expressions (currently only of type int).
*Invalid constant shift counts (negative, or >= the width of the type)
*Division by (constant) zero.

These (mainly the first two) can be indicative of code that was designed for larger type sizes and needs changes to support 16-bit int.

    This parses out the xprintf / xscanf format string and compares it with the function arguments.

    enabled via #pragma lint 16.

4cff395745 Move some code from the blank segment to named load segments.
This frees up some space in the blank segment for more static data.

a4bffe65e5 Increase the limit on the number of intermediate code labels in a function from 2400 to 3200.
This is necessary to compile some very large functions, such as the main interpreter loop in Git.

This consumes about 8K of extra memory for the additional label records.

05a0ce738a Permit unions to be initialized by assignment from expressions of the appropriate union type.
This patch should also permit the union initialization code to handle unions containing bit fields, but for the time being they are still prohibited by code elsewhere in the compiler.
