Add unwind information for r7 in arm syscalls. It turns out that clang can emit code where the sp is saved in the r7 register on arm. Unfortunately, a lot of our syscalls overwrite that value while the syscall is executing, so unwinding through that syscall fails. Update the syscall generation code to add unwinding information for these uses. Bug: 28411713 (cherry picked from commit 6e45d37decbbaf78ed4685213aebb1c9b5ccf8c2) Change-Id: Ib775effc44c4113735fe9032b0602b9d63e3e390

Ensure __set_errno is still visible on LP32. The use of the .hidden directive to avoid going via the PLT for __set_errno had the side-effect of actually making __set_errno hidden (which is odd because assembler directives don't usually affect symbols defined in a different file --- you can't even create a weak reference to a symbol that's defined in a different file). This change switches the system call stubs over to a new always-hidden __set_errno_internal and has a visible __set_errno on LP32 just for binary compatibility with old NDK apps. (cherry-pick of 7efad83d430f4d824f2aaa75edea5106f6ff8aae.) Bug: 17423135 Change-Id: I6b6d7a05dda85f923d22e5ffd169a91e23499b7b
