GCC's libgcc exports a few ARM-specific symbols for ARM EABI, AEABI, or EHABI or whatever it's called. Export the same ones from LLVM-libunwind's libgcc_s, on ARM. As part of this, convert libgcc_s from a direct Version.map to one constructed from component Symbol.map files. This allows the ARM-specific Symbol.map to be included only on ARM. Fix ARM-only oddities in struct name/aliases in LLVM-libunwind to match non-ARM definitions and ARM-specific expectations in libcxxrt / libcompiler_rt. No functional change intended for non-ARM architectures. This commit does not actually flip the switch for ARM defaults from libgcc to llvm-libunwind, but makes it possible (to compile, anyway).
