Christophe Lyon May 9, 2022, 2:35 p.m. UTC 
Some tests for the BID format are currently restricted to i?86 and
x86_64, but they also pass on AArch64, so this patch enables them.

Since all these tests are related to the BID format, it seems useful
to introduce a new effective-target (dfp_bid) instead of adding
aarch64 to the current target list.

2022-04-28  Christophe Lyon  <christophe.lyon@arm.com>

	gcc/doc/
	* sourcebuild.texi (Decimal floating point attributes): Document
	dfp_bid effective-target.

	gcc/testsuite/
	* lib/target-supports.exp (check_effective_target_dfp_bid): New.
	* gcc.dg/dfp/bid-non-canonical-d128-1.c: Use dfp_bid
	effective-target.
	* gcc.dg/dfp/bid-non-canonical-d128-2.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d128-3.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d128-4.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d32-1.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d32-2.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d64-1.c: Likewise.
	* gcc.dg/dfp/bid-non-canonical-d64-2.c: Likewise.
