a62270de2c Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

71d1cca7ef Temporarily Revert "Add basic loop fusion pass."
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

3be32ec89b [SafeStack] Set debug location for calls to __safestack_pointer_address.
Otherwise, the debug info is incorrect.  On its own, this is mostly
harmless, but the safe-stack also later inlines the call to
__safestack_pointer_address, which leads to debug info with the wrong
scope, which eventually causes an assertion failure (and incorrect debug
info in release mode).

b310adabbe [safestack] Make sure the unsafe stack pointer is popped in all cases
The unsafe stack pointer is only popped in moveStaticAllocasToUnsafeStack so it won't happen if there are no static allocas.

82c98de471 [safestack] Fix compiler crash in the presence of stack restores.
A use can be emitted before def in a function with stack restore
points but no static allocas.

c8b423f66c Android support for SafeStack.
Add two new ways of accessing the unsafe stack pointer:

* At a fixed offset from the thread TLS base. This is very similar to
  StackProtector cookies, but we plan to extend it to other backends
  (ARM in particular) soon. Bionic-side implementation here:
  https://android-review.googlesource.com/170988.
* Via a function call, as a fallback for platforms that provide
  neither a fixed TLS slot, nor a reasonable TLS implementation (i.e.
  not emutls).

This is a re-commit of a change in r248357 that was reverted in
r248358.
