[PATCH 1/2] RISC-V/testsuite: Widen coverage for pr105314.c

["Maciej W. Rozycki" <macro@embecosm.com>]

The optimization levels pr105314.c is iterated over are needlessly 
overridden with "-O2", limiting the coverage of the test case to that 
level, perhaps with additional options the original optimization level 
has been supplied with.  We could prevent the extra iterations other 
than "-O2" from being run, but the transformation made by if-conversion 
is also expected to happen at other optimization levels, so include them 
all, and also make sure no reverse-condition branch appears in output, 
moving the `dg-final' command to the bottom, as with most test cases.

	gcc/testsuite/
	* gcc.target/riscv/pr105314.c: Replace `dg-options' command with
	`dg-skip-if'.  Also reject "bne" with `dg-final'.

Hi,

 Technically it's not a single self-contained change and it could be 3
instead, but I think there's little point in splitting it further.
