[patch, testsuite] Remove superfluous -std={c99,gnu99} in libgomp.c

[Tom de Vries <Tom_deVries at mentor dot com>]

Hi,

this patch removes a superfluous -std=c99 or -std=gnu99 setting in the 
libgomp/testsuite/libgomp.c testcases (and a superfluous -fopenmp 
setting in some cases as well).

The setting is superfluous because -std=gnu11 is the new default for C 
mode, which allows loop initial declaration.

In a few cases (for-{1,2,3}.c, pr35625.c)  we remove the whole 
dg-options line which did not have an -On setting, which means the 
optimization level at which the testcase compiles is changed from -O0 to 
the default -O2.

Tested with a c build. for-2.c fails, filed as PR66429 - 'ICE in 
expand_GOMP_SIMD_LAST_LANE'.

OK for trunk?

Thanks,
- Tom
