Issue Description:

The following IRGen test failures are seen when Swift 5.0 toolchain is built on PowerPC64LE.

Invoked the build-toolchain to run the tests as follows :-
utils/build-toolchain srtbundle --test

**Following are the IRGen test failures:-

Swift(linux-powerpc64le) :: IRGen/class_resilience_objc.swift
Swift(linux-powerpc64le) :: IRGen/big_types_corner_cases.swift
Swift(linux-powerpc64le) :: IRGen/clang_inline_opt.swift
Swift(linux-powerpc64le) :: IRGen/errors.sil
Swift(linux-powerpc64le) :: IRGen/objc_simd.sil
Swift(linux-powerpc64le) :: IRGen/objc_properties_jit.swift
Swift(linux-powerpc64le) :: IRGen/pic.swift

Are these tests valid for PowerPC64LE?

Attached are the error details of the failing tests.

IRGenTestFailures.txt

Of these tests failing above, IRGen/clang_inline_opt.swift seems to be unsupported for PowerPC64LE as it targets 32 bits. Unsupporting it as below helps resolve the test:-

// UNSUPPORTED: CPU=powerpc64le

These seem like a set that falls under "if it works on x86_64 Linux it should work on PowerPC64LE Linux".
