This reverts commit a4d5fd4d2ee9470e55345a9540f6b6fb6faf66e1.
The above commit breaks greendragon lldb bots:

I found this PR to be the offending one after using git bisect with the
cmake invocation:
cmake -G Ninja ../llvm -DCMAKE_BUILD_TYPE=Release
-DCMAKE_EXPORT_COMPILE_COMMANDS=ON
'-DLLVM_TARGETS_TO_BUILD=X86;ARM;AArch64'
-DLLVM_ENABLE_ASSERTIONS:BOOL=TRUE
-DLLVM_ENABLE_MODULES=On
-DLLVM_ENABLE_PROJECTS='clang;lld;lldb;cross-project-tests'
-DLLVM_VERSION_PATCH=99
'-DLLVM_ENABLE_RUNTIMES=libcxx;libcxxabi;compiler-rt'
and running
ninja lib/CodeGen/CMakeFiles/LLVMCodeGen.dir/CodeGenPassBuilder.cpp.o
Just copy the `runOnFunction` method from `SafeStackLegacyPass` and
remove the workaround for computing analysis lazily, the analysis result
in new pass manager is computed lazily by default.
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.
llvm-svn: 358546
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.
