testsuite: Require lto-plugin support in gcc.dg/lto/modref-3 etc. [PR98237]
gcc.dg/lto/modref-3 etc. FAIL on Solaris with the native linker:
FAIL: gcc-dg-lto-modref-3-01.exe scan-wpa-ipa-dump modref "parm 1 flags: no_direct_clobber no_direct_escape"
FAIL: gcc-dg-lto-modref-4-01.exe scan-wpa-ipa-dump modref "parm 1 flags: no_direct_clobber no_direct_escape"
FAIL: gcc.dg/lto/modref-3 c_lto_modref-3_0.o-c_lto_modref-3_1.o execute -O2 -flto-partition=max -fdump-ipa-modref -fno-ipa-sra -fno-ipa-cp -flto
FAIL: gcc.dg/lto/modref-4 c_lto_modref-4_0.o-c_lto_modref-4_1.o execute -O2 -flto-partition=max -fdump-ipa-modref -fno-ipa-sra -flto
The issue is that the tests require the linker plugin, which isn't
available with Solaris ld. Thus, it also FAILs when gcc is configured
with --disable-lto-plugin.
This patch thus declares the requirement. As it turns out, there's an
undocumented dg-require-linker-plugin already, but I introduce and use
the corresponding effective-target keyword and document both.
Given that the effective-target form is more flexible, I'm tempted to
remove dg-require-* with an empty arg as already mentioned in
sourcebuild.texi. That is not this patch, however.
Tested on i386-pc-solaris2.11 with ld and gld.
