[PATCH] Arm - exceptions stack pointer initialization hook

[Alexander Fedotov]

Eventually I want to push all the changes from there:
1. https://github.com/alfedotov/newlib/commit/58ce6f19eb457a2c2b700dfe71798ef09ba63e10
2. https://github.com/alfedotov/newlib/commit/4cabb1f7587304d1c891da59bd1871fcc8668ae5
3. https://github.com/alfedotov/newlib/commit/7d38977d4baaecb43fc47f34d721a3df23334400
4. https://github.com/alfedotov/newlib/commit/e8f094f6729ade24a149d1d6816876e7ccadae0a

General idea behind of all these changes is to provide hooks for
flexibility (including semihosting when debug tap is used) and improve
readability of existing crt0 code. At the moment it is a total mess of
ifdefs...
