i386: Update INCOMING_FRAME_SP_OFFSET for exception handler
Since there is an extra error code passed to the exception handler,
INCOMING_FRAME_SP_OFFSET is return address plus error code for the
exception handler. This patch updates INCOMING_FRAME_SP_OFFSET to
the correct value for the exception handler.
This patch exposed a bug in DWARF stack frame CFI generation, which
assumes that INCOMING_FRAME_SP_OFFSET is the same for all functions:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=81570
It sets and caches the incoming stack frame offset with the same
INCOMING_FRAME_SP_OFFSET for all functions. When there are both
exception handler and normal function in the same input, the wrong
incoming stack frame offset is used for exception handler or normal
function, which leads to

compiler: track placeholder pointer types for conversion
We recently started walking through the hash table of pointer types to
finalize them. Unfortunately it is possible to create a new pointer
type while finalizing an existing one (test case: test/fixedbugs/issue5291)
and that breaks the iteration. So, instead, keep a list of
placeholder pointer types, and iterate through them while permitting
the list to be extended as we go.

compiler: use a single temporary for calls with multiple results
For calls that return multiple results we used to create a temporary
of struct type to hold the results, and also create a separate
temporary for each result. Then the call expression would copy each
result out of the struct to the temporary, and Call_result_expression
would refer to the desired temporary.
Simplify this to just use a single temporary of struct type, and
change Call_result_expression to fetch a field of the struct.
This may reduce some incorrect tree sharing in the backend code.

During combine GCC tries to merge CMP (with zero) and AND into a TST. However,

[Patch (preapproved)] Guard Copy Header pass on
While answering a user question on the equivalence of
-ftree-loop-vectorize + -ftree-slp-vectorize and -ftree-vectorize I
spotted one case which broke the equivalence. pass_ch::process_loop_p
was guarded on flag_tree_vectorize, meaning you would get it for
-ftree-vectorize, but not for -ftree-loop-vectorize/-ftree-slp-vectorize.
This patch fixes that, getting rid of the only use of flag_tree_vectorize
in the code base.

S/390: Fix PR81534
The HI/QI atomic_fetch_<atomic><mode>" expander accepted symbolic

[rs6000] Avoid rotates of floating-point modes
The little-endian VSX code uses rotates to swap the two 64-bit halves of
128-bit scalar modes. This is fine for TImode and V1TImode, but it
isn't really valid to use RTL rotates on floating-point modes like
KFmode and TFmode, and doing that triggered an assert added by the
SVE series. This patch uses bit-casts to V1TImode instead.
