testsuite: RISC-V: Add effective target for E ABI variant

Browse source 
Add new effective target check for either ILP32E or ILP64E ABI variants.

Initial implementation only checks for RV32E or RV64E ISA, which in turn
implies that ILP32E/ILP64E ABI is used.  The RV32I+ILP32E and
RV64I+ILP64E combinations are not yet caught by the check, but they
do not seem to be widely used currently.

gcc/testsuite/ChangeLog:

	* lib/target-supports.exp (check_effective_target_riscv_abi_e):
	New procedure.
