Centralise clearing hardware capabilities with Sun ld
gcc:
* configure.ac ($gcc_cv_ld_clearcap): New test.
* configure: Regenerate.
* config.in: Regenerate.
* config/sol2.opt (mclear-hwcap): New option.
* config/sol2.h (LINK_CLEARCAP_SPEC): Define.
* config/sol2-clearcap.map: Moved here from
testsuite/gcc.target/i386/clearcap.map.
* config/sol2-clearcapv2.map: Move here from
gcc.target/i386/clearcapv2.map.
* config/t-sol2 (install): Depend on install-clearcap-map.
(install-clearcap-map): New target.
* doc/invoke.texi (Option Summary, Solaris 2 Options): Document
-mclear-hwcap.
gcc/testsuite:
* lib/clearcap.exp: New file.
* gcc.dg/vect/vect.exp: Load clearcap.exp.
Remove clearcap_ldflags handling.
Call clearcap-init, clearcap-finish.
* gcc.target/i386/i386.exp: Likewise.
* gcc.target/i386/clearcap.map: Move to ../config/sol2-clearcap.map.
* gcc.target/i386/clearcapv2.map: Move to
../config/sol2-clearcapv2.map.
* gcc.target/x86_64/abi/avx/abi-avx.exp: Likewise.
* gcc.target/x86_64/abi/avx512f/abi-avx512f.exp: Likewise.
libitm:
* acinclude.m4 (LIBITM_CHECK_LINKER_HWCAP): Check for
-mclear-hwcap instead.
* configure: Regenerate.
* clearcap.map: Remove.
