target abi Implement cfg(target_abi) (RFC 2992) Add an `abi` field to `TargetOptions`, defaulting to "". Support using `cfg(target_abi = "...")` for conditional compilation on that field. Gated by `feature(cfg_target_abi)`. Add a test for `target_abi`, and a test for the feature gate. Add `target_abi` to tidy as a platform-specific cfg. Update targets to use `target_abi` All eabi targets have `target_abi = "eabi".` All eabihf targets have `target_abi = "eabihf"`. `armv6_unknown_freebsd` and `armv7_unknown_freebsd` have `target_abi = "eabihf"`. All abi64 targets have `target_abi = "abi64"`. All ilp32 targets have `target_abi = "ilp32"`. All softfloat targets have `target_abi = "softfloat"`. All *-uwp-windows-* targets have `target_abi = "uwp"`. All spe targets have `target_abi = "spe"`. All macabi targets have `target_abi = "macabi"`. aarch64-apple-ios-sim has `target_abi = "sim"`. `x86_64-fortanix-unknown-sgx` has `target_abi = "fortanix"`. `x86_64-unknown-linux-gnux32` has `target_abi = "x32"`. Add FIXME entries for targets for which existing values need to change once `cfg_target_abi` becomes stable. (All of them are tier 3 targets.) Add a test for `target_abi` in `--print cfg`. |

rustc_target contains some very low-level details that are
specific to different compilation targets and so forth.
