PR modula2/116073 invalid rtl sharing compiling FileSystem.mod caused by ext-dce
The bug fixes to PR modula2/118010 and PR modula2/118183 uncovered a bug
in the procedure interface to lseek which uses SYSTEM.COFF_T rather than
SYSTEM.CSSIZE_T. This patch sets the default size for COFF_T to the same
as CSSIZE_T.
gcc/ChangeLog:

PR modula2/118183
PR modula2/116073
* doc/gm2.texi (-fm2-file-offset-bits=): Change the default size
description to CSSIZE_T.
Add COFF_T to the list of data types exported by SYSTEM.def.
gcc/m2/ChangeLog:
PR modula2/118010
PR modula2/118183
PR modula2/116073
* gm2-compiler/M2Options.mod (OffTBits): Assign to 0.
* gm2-gcc/m2type.cc (build_m2_specific_size_type): Ensure that
layout_type is called before returning c.
(build_m2_offt_type_node): If GetFileOffsetBits returns 0 then
use the type size of ssize_t.
