* libc/machine/mips/setjmp.S: Fix definition of macro FPR_LAYOUT
	for ABI == N32.
	* syscalls.cc (try_to_bin): Take additional parameter to get file open
	flags.  If the file to move to the bin has been opened casesensitive,
	reopen it caseinsensitive.  Explain why.  Revert the default name of
	the Vista-and-later recycler to mixed case for readability.
	(unlink_nt): Call try_to_bin with file open flags as evaluated.
	* syscalls.cc (try_to_bin): Drop fh_dup, reuse tmp_fh instead.
	* syscalls.cc (try_to_bin): Enhance debug output in case reopen fails.
