[LTO][clang] Teaching Clang to Pass Plugin Options to the AIX Linker This patch teaches `clang` to use the prefix `-bplugin_opt:` (instead of `-plugin-opt`) on AIX, when passing plugin options to the linker. This patch follows https://reviews.llvm.org/D134668. We put the code that decides what plugin option prefix to use at the top of the function `tools::addLTOOptions`. The plugin option prefix, the mcpu prefix, and the opt level prefix are different on AIX. We thought about choosing the strings in a function that reads the linker name and the target triple, or we could push the logic into different derived `ToolChain` classes. But this logic would not be used anywhere else, so these alternatives looked too complicated for what they did. Therefore we are doing it the current way. That said, I am all ears for suggestions to improve this code! Subsequent code uses the `PluginOptPrefix` variable consistently instead of the hardcoded `-plugin-opt`.

[clang][LTO][NFC] Adding More Tests for AIX Options This patch adds more tests for AIX. It follows https://reviews.llvm.org/D134820 which added a minimal set of tests for the newly added AIX options. These new tests were originally created by https://reviews.llvm.org/D119109. Since we do not plan to land https://reviews.llvm.org/D119109 in its current shape to add the AIX specific options, we incorporate the relevant tests developed.

[AIX][LTO] Enabling Context Sensitive PGO Options This patch enables context sensitive PGO (CSPGO) for LTO on AIX. Two parts are involved: # Frontend logic is added so libLTO can understand the CSPGO related options. # Two options are added to the backend so that the LTOCodeGenerator can understand the CSPGO related options and make use of them.
