This makes vectorization properly assign vector types to PHI

At least here newlib is build without HAVE_POSIX / 'posix' subdirectory

For nvptx, the same issue exists – and there 'omp declare variant' is used
to call a burn-cycles loop as replacement.
Affects target-32.c and thread-limit-2.c.

This adds preprocessor support for header units. Every #include

This fixes an ODR violation in the AIX headers that is detected by C++

Hi,
The insn type of p8_mtvsrd_df looks missed to be updated
with mtvsr. Here I supposed mtvsrd's all usages should
be with the same insn type.
This patch is to fix its current insn type mfvsr by mtvsr.
Is it ok for trunk?

Kewen

So I didn't stay up late to work from Pago Pago this year and beat the
stage1 close, but I do want to flush out the removal of cc0 from the H8
port this cycle. Given these patches only affect the H8 and the H8
would be killed this cycle without the conversion, I think this is
suitable even though
Here is another version of the patch. The
only difference is the additional the check
using 'tree_ssa_useless_type_conversion'.
Best,
Martin
