Fix compile options of pr110279-1.c and pr110279-2.c
The two testcases are for targets that support FMA. And
pr110279-2.c assumes reassoc_width of FMUL to be 4.
This patch adds missing options, to fix regression test failures
on nvptx/GCN (default reassoc_width of FMUL is 1) and x86_64
(need "-mfma").
gcc/testsuite/ChangeLog:
* gcc.dg/pr110279-1.c: Add "-mcpu=generic" for aarch64; add
"-mfma" for x86_64.
* gcc.dg/pr110279-2.c: Replace "-march=armv8.2-a" with
"-mcpu=generic"; limit the check to be on aarch64.
