[Bug bootstrap/40268] New: continued build failures from PR39791 and PR40061 fixes

["mikpe at it dot uu dot se" <gcc-bugzilla at gcc dot gnu dot org>]

gcc-4.3-20090524 fails to build for target=alpha-unknown-linux:

/tmp/gcc-4.3-20090524/gcc/dwarf2out.c: In function 'add_subscript_info':
/tmp/gcc-4.3-20090524/gcc/dwarf2out.c:11328: error: break statement not within
loop or switch

gcc-4.3.3 and earlier build fine so this is a regression.

The problem is that the PR39791 fix put a break statement in a block which is a
loop body only when !MIPS_DEBUGGING_INFO. This and an undeclared variable issue
were reported as PR40061, but the fix for PR40061 only fixed the undeclared
variable issue, not the invalid break statement issue.

The break issue could be fixed by turning this block into a loop body also in
the !MIPS_DEBUGGING_INFO case, but that looks like it will require more #ifdefs
and local variables. So I suggest to just #ifdef the break statement. I'm
attaching patch which does just that.
