After the register allocator changes of r268705 we need to update a few tests
with new output.
In all cases the compiler is now generating the expected code, since the tests
are all float16 testcases using a hard-floar abi, we expect that actual fp16
instructions are used rather than using integer loads and stores. Because of
we also save on some mov.f16s that were being emitted before to move between
the two.
The aapcs cases now match the f32 cases in using floating point operations.

Inline PLT calls need PLT to be an array of addresses. PowerPC 32-bit
bss-plt works differently, so this patch disables inline PLT calls
when -mbss-plt. The patch also adds support for a new -mno-pltseq
option, which may be required when linking with -mbss-plt code.

Instead of a single test that only checks whether <regex> can be
included in Parallel Mode, add tests for each of C++11/C++14/C++17 that
check whether <bits/extc++.h> is compatible with _GLIBCXX_PARALLEL.
This increases the coverage to (almost) all headers.
If <omp.h> is not available then the tests will trivially pass, because
we don't care about compatibility with _GLIBCXX_PARALLEL in that case.

Fixes lack of r30 save/restore on
// -m32 -fpic -ftls-model=initial-exec
__thread char* p;
char** f1 (void) { return &p; }
and
// -m32 -fpic -msecure-plt
extern int foo (int);
int f1 (int x) { return foo (x); }
These are both caused by save_reg_p returning false when the pic
offset table reg (r30 for ABI_V4) was used, due to the logic not
exactly matching that in rs6000_emit_prologue to set up r30.
I also noticed that save_reg_p isn't following the comment regarding
calls_eh_return (since svn 267049, git 0edf78b1b2a0), and the comment
needs tweaking too. For why the revised comment is correct, grep for
saves_all_registers in lra.c, and yes, we do want to save the pic
offset table reg for eh_return.
