These were previously re-enabled in d771f54107c, but had to be disabled again
in 2060a72b4d7 due to test failures.
This is a next step to landing https://reviews.llvm.org/D148192, which adds
a skeleton JITLink backend for PowerPC.
The fixes for those failures were (1) to explicitly specify IsLittleEndian =
true for the MachO YAML testcases, (2) disable some example tests for examples
that aren't supported on PowerPC yet, and (3) fixing the endianness of a
relocation read/write (for ELF R_AARCH64_TSTBR14) in RuntimeDyldELF.
This is for case when native target like X86 is not in LLVM_TARGETS_TO_BUILD.
Right now LLVM_DEFAULT_TARGET_TRIPLE is set to LLVM_HOST_TRIPLE even when native target is not enabled,
As a result, many lit tests will fail because default_triple is set for lit test but not enabled when build LLVM.

The example demonstrates how to use a module summary index file produced for ThinLTO to:
* find the module that defines the main entry point
* find all extra modules that are required for the build
A LIT test runs the example as part of the LLVM test suite [1] and shows how to create a module summary index file.
The code also provides two Error types that can be useful when working with ThinLTO summaries.
