Some x86 tests of stack realignment, that disaligned the stack with
pushes and pops, failed when the compiler was configured to tune for a
target that preferred to accumulate outgoing arguments: the stack
space is reserved before the asm push, the call sequence overwrites
the saved register, and then the asm pop restores the overwritten
value.  Since that's a call-preserved register in 32-bit mode, it
should be preserved unchanged, but isn't.

Merely changing the register to a call-clobbered one would be enough,
but the tests would remain fragile and prone to failure due to other
optimizations, so I arranged for the compiler to be made aware of the
register used for the push and the pop, so it won't use it for
something else, and forced the function to use a frame pointer, so
that it won't use stack pointer offsets for local variables: the
offsets would likely be wrong between the asm push and pop.

This caches a check for the requirement to indirect a symbol in the Darwin

We want to improve the detection and caching of symbol-properties
so that (a) we can make the compiler's output match the platform
norms (b) we can improve efficiency by checking flags instead of
inspecting strings. (c) The fix for PR71767 was a largish hammer
and we want to reduce the number of symbols that are made linker-
visible.

This first patch is largely typographical changes with no functional
difference intended:

- Tries to ensure that there's no overlap between the symbols used in
the Mach-O case and those declared in the i386 or rs6000 port trees.

 - Some improvement to comments.

- Makes the naming of the symbol flags consistent with other uses.

z13 supports only non-signaling vector comparisons.  This means we
cannot vectorize LT, LE, GT, GE and LTGT when compiling for z13.
However, we cannot express this restriction today: the code only checks
whether vcond$a$b optab exists, but this does not say anything about the
operation.

Introduce a function that checks whether back-end supports vector
comparisons with individual rtx codes by matching vcond expander's third
argument with a fake comparison with the corresponding rtx code.

This is not necessary and makes the resulting GIMPLE harder to analyze.
Change the gimplifier so as to allow COND_EXPR and VEC_COND_EXPR
conditions to trap.

This patch takes special care to avoid introducing trapping comparisons
in GIMPLE_COND.  They are not allowed, because they would require 3
outgoing edges (then, else and EH), which is awkward to say the least.
Therefore, computations of such conditions should live in their own basic
blocks.

2019-10-07  Ilya Leoshkevich  <iii@linux.ibm.com>

	PR target/77918
	* gimple-expr.c (gimple_cond_get_ops_from_tree): Assert that the
	caller passes a non-trapping condition.
	(is_gimple_condexpr): Allow trapping conditions.
	(is_gimple_condexpr_1): New helper function.
	(is_gimple_condexpr_for_cond): New function, acts like old
	is_gimple_condexpr.
	* gimple-expr.h (is_gimple_condexpr_for_cond): New function.
	* gimple.c (gimple_could_trap_p_1): Handle COND_EXPR and
	VEC_COND_EXPR. Fix an issue with statements like i = (fp < 1.).
	* gimplify.c (gimplify_cond_expr): Use
	is_gimple_condexpr_for_cond.
	(gimplify_expr): Allow is_gimple_condexpr_for_cond.
	* tree-eh.c (operation_could_trap_p): Assert on COND_EXPR and
	VEC_COND_EXPR.
	(tree_could_trap_p): Handle COND_EXPR and VEC_COND_EXPR.
	* tree-ssa-forwprop.c (forward_propagate_into_gimple_cond): Use
	is_gimple_condexpr_for_cond, remove pointless tmp check
	(forward_propagate_into_cond): Remove pointless tmp check.
