arm: Fixes for asm-flags vs thumb1 and ilp32
Thumb1 cannot support asm-flags currently, because we don't expose the
flags register to the compiler. Disable the support for that case.
Adjust the asm-flag-6 test for aarch64 ilp32 correctness.
gcc/
* config/arm/arm-c.c (arm_cpu_builtins): Use def_or_undef_macro
to define __GCC_ASM_FLAG_OUTPUTS__.
* config/arm/arm.c (thumb1_md_asm_adjust): New function.
(arm_option_params_internal): Swap out targetm.md_asm_adjust
depending on TARGET_THUMB1.
* doc/extend.texi (FlagOutputOperands): Document thumb1 restriction.
gcc/testsuite/
* testsuite/gcc.target/arm/asm-flag-3.c: Skip for thumb1.
* testsuite/gcc.target/arm/asm-flag-5.c: Likewise.
* testsuite/gcc.target/arm/asm-flag-6.c: Likewise.
* testsuite/gcc.target/arm/asm-flag-4.c: New test.
* testsuite/gcc.target/aarch64/asm-flag-6.c: Use %w for
asm inputs to cmp instruction for ILP32.
