(FLO_union_type): Remove bitfields to set sign, exponent, and
mantissa, and add value_raw field, which is an integer of the
appropriate type. If _DEBUG_BITFLOAT is defined, provide little and
big endian bitfields. If the macro FLOAT_BIT_ORDER_MISMATCH is
defined, use explicit bitfields.
(pack_d, unpack_d): Switch to use value_raw and explicit shifts and
masks so that we don't have to worry about whether the target is big
or little endian unless FLOAT_BIT_ORDER_MISMATCH is defined. If
single precision floating point, rename to pack_f and unpack_f, so
there is no confusion in the debugger.

(xcoff_inlining): New variable, used in place of
xcoff_current_include_file when determining whether to use absolute
line numbers.
(xcoffout_source_file): Switched to using xcoff_inlining to determine
when to emit .bi/.ei directives.

[L_udivdi3 || L_divdi3 || L_umoddi3 || L_moddi3] (__udivmoddi4):
Define this `static inline' when defining these, so they all remain
leaf functions.
From-SVN: r10305
(stmts, stmt_or_label): Use new member to avoid lexical lookahead hack.
(lineno_stmt_or_labels): New rule.
(lineno_stmt_or_label, stmt_or_label): Yield nonzero if it ends in a label.
From-SVN: r10302
(push_reload): Add case for output reload of a SUBREG
of a hard reg when output mode is invalid for that mode.
In both that case and existing case for in, don't remove SUBREG.
From-SVN: r10294
(emit_reload_insns): Do nothing for SUBREG whose operand is unused
subsequently.
In secondary reload case, if paradoxical SUBREG for output, reload thing
inside SUBREG, just like gen_reload.
From-SVN: r10284
(note_level_for_for): New function.
(poplevel): Special processing if is_for_scope.
(pushdecl): Warn if for-scope variable shadows local.
From-SVN: r10273
(flag_new_for_scope): Add a new mode that follows ANSI
for-scoping, but supports (and warns about) old programs.
Make the new mode (with value 1) the default.
(lang_f_options): The on-value for flag_new_for_scope is now 2.
From-SVN: r10272
(report_error_function): Don't attempt to use input file stack to
identify nesting of #include's if file name oflocation diagnosed is
not same as input_filename.
From-SVN: r10271
(decrement_and_branch_until_zero): Use arithmetic_comparison_operator
to decide if there is comparison suitable to be expressed by condition
code from an arithmetic op.
From-SVN: r10269
(movdi-1, movdf-1): Make conditional on reload_completed, delete
conditions checking for pseudo registers and Q addresses. Add code to
handle SUBREG.
