Good point.
Your remark made me notice that the callers of arm_v8_1m_lob_hw were
also "v8_1", so I renamed them as attached.

commit 1059695c96da8a53806109f97d1dce455a252496

testsuite: arm: rename arm_v8_1_lob_ok into arm_v8_1m_lob_hw
All arm effective-targets using check_runtime use the "_hw" or
"_multilib" suffix, so rename arm_v8_1_lob_ok into arm_v8_1m_lob_hw
for consistency.
Since "lob" applies only to M-profile, replace v8_1 with v8_1m in
arm_v8_1_lob_ok, arm_thumb2_no_arm_v8_1_lob and
arm_thumb2_ok_no_arm_v8_1_lob.
gcc/testsuite/ChangeLog
* lib/target-supports.exp: Rename arm_v8_1_lob_ok into
arm_v8_1m_lob_hw.
Rename arm_thumb2_no_arm_v8_1_lob into
arm_thumb2_no_arm_v8_1m_lob.
Rename arm_thumb2_ok_no_arm_v8_1_lob into
arm_thumb2_ok_no_arm_v8_1m_lob.
* gcc.target/arm/lob1.c: Likewise.
* gcc.target/arm/lob6.c: Likewise.
* gcc.target/arm/ivopts.c: Likewise.
* gcc.target/arm/unsigned-extend-2.c: Likewise.
