236ff62678 Fix llvm-libunwind userspace build on ARM
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).

c5ddd11381 Support armv7 builds for userland
Make armv7 as a new MACHINE_ARCH.

Copy all the places we do armv6 and add armv7 as basically an
alias. clang appears to generate code for armv7 by default. armv7 hard
float isn't supported by the the in-tree gcc, so it hasn't been
updated to have a new default.

Support armv7 as a new valid MACHINE_ARCH (and by extension
TARGET_ARCH).

Add armv7 to the universe build.

860be99e46 In compiler-rt, a few assembler implementations for i386 floating point
conversion functions use SSE2 instructions, but these are not guarded by
#ifdef __SSE2__, and there is no implementation using general purpose
registers.  For these functions, use the generic C variants instead,
otherwise they will cause SIGILL on older processors.

4aaf3ccbdf Include {u,}{div,mod}si3() on mips in libcompiler_rt.
These builtins were listed in the mips-specific Symbol.map for libc but
were not implemented.  Compiling mips with recent clang requires these
symbols.
