Revert "[OpenMP] Remove noinline attributes in the device runtime"
The behaviour of this patch is not great, but it has some side-effects
that are required for OpenMPOpt to work. The problem is that when we use
`-mlink-builtin-bitcode` we only import used symbols from the runtime.
Then OpenMPOpt will insert calls to symbols that were not previously
included. This patch removed this implicit behaviour as these functions
were kept alive by the `noinline` simply because it kept calls to them
in the module. This caused regression in some tests that relied on some
OpenMPOpt passes without using LTO. Reverting for the LLVM15 release but
will try to fix it more correctly on main.
This reverts commit d61d72dae604c3258e25c00622b1a85861450303.
Fixes #56752
(cherry picked from commit b08369f7f288b6efb0897953da42ed54e60cfc0b)

[OpenMP] Only strip runtime attributes if needed
Summary:
Currently in OpenMPOpt we strip `noinline` attributes from runtime
functions. This is here because the device bitcode library that we link
has problems with needed definitions getting prematurely optimized out.
This is only necessary for OpenMP offloading to GPUs so we should narrow
the scope for where we spend time doing this. In the future this
shouldn't be necessary as we move to using a linked library rather than
pulling in a bitcode library in Clang.
