Matthias Krüger b3948e5f10 Rollup merge of #149679 - pmur:murp/ppc-inline-improvements, r=Amanieu
Restrict spe_acc to PowerPC SPE targets

Update the tests, add powerpc-*-gnuspe testing, and create a distinct clobber_abi list for PowerPC SPE targets.

Note, the SPE target does not have vector, vector-scalar, or floating-point specific registers.

The files here use the LLVM FileCheck framework, documented at https://llvm.org/docs/CommandGuide/FileCheck.html.

One extension worth noting is the use of revisions as custom prefixes for FileCheck. If your codegen test has different behavior based on the chosen target or different compiler flags that you want to exercise, you can use a revisions annotation, like so:

// revisions: aaa bbb
// [bbb] compile-flags: --flags-for-bbb

After specifying those variations, you can write different expected, or explicitly unexpected output by using <prefix>-SAME: and <prefix>-NOT:, like so:

// CHECK: expected code
// aaa-SAME: emitted-only-for-aaa
// aaa-NOT:                        emitted-only-for-bbb
// bbb-NOT:  emitted-only-for-aaa
// bbb-SAME:                       emitted-only-for-bbb
