Oliver Stannard 1224c809f1 [libunwind][ARM] Add support for Thumb1 targets ... The Thumb1 version of the code for saving and restoring the unwind context has a few bugs which prevent it from working: * It uses the STM instruction without writeback, which is not valid for Thumb1 (It was introduced in Thumb2). * It only saves/restores the low 8 registers, the sp and the lr, so if a program uses r8-r12 they will not be correctly restored when throwing an exception. There aren't currently any Thumb1 build-bots to test this, but we have been successfully running the libc++abi and libc++ test suites on Cortex-M0 models, as well as some other test suites that use C++ exceptions on a downstream version of libunwind with this patch applied.
