[PATCH] c++: testsuite: require lto_incremental in pr90990_0.C

[Alexandre Oliva via Gcc-patches]

Other LTO tests that use -r require the lto_incremental effective
target.  I suppose pr90990_0.C is missing it due to an oversight.
This patch arranges for this test to also be skipped on
non-lto_incremental targets.

Regstrapped on x86_64-linux-gnu, also tested with a cross to
aarch64-rtems6.  Ok to install?
