virtual_operand_p handled SSA names by looking at the flags of the
underlying variable. This seems to be a relatively common source
of cache misses, mainly because virtual_operand_p is the first thing
tested by is_gimple_reg.
This patch caches the information in the SSA name itself. Several
flags seem to be free so the patch arbitrarily uses public_flag.
Tested on aarch64-linux-gnu and x86_64-linux-gnu. It improves
compile time by a small (<1%) but reproducable amount on the
tests I've tried.

Change Struct_type::do_mangled_name to incorporate the field
names even for hidden symbols. This is needed in cases where
a package imports a type "S" that has an anonymous struct, e.g.
// imported from some other package
type S struct {
X struct{ _ struct{} }
}
and then defines a local type that uses a structurally identical
anonymous struct, e.g.
// defined locally
type T struct {
U struct{ _ struct{} }
}
In the case above both types triggered the creation of hash/equal
methods, but the method names were clashing (since both structs
had the same mangled name).

When pushing a value into the literal pool the resulting decl might
get a higher alignment than the original expression depending on how a
target defines CONSTANT_ALIGNMENT. Generating an RTX for the constant
pool access we currently use the alignment from the original
expression. Changed with the attached patch.
This fixes a GCC 6 regression for S/390. For arrays of string
constants as in the attached testcase encode_section_info is not able
to figure out that the constant pool slot is already properly aligned
since the mem_align field in the rtx is not set properly.

All feedback from the earlier version has been taken into account now.
This patch adds the -fasynchronous-unwind-tables option to compilations when
the -fsanitize=address option is seen but not if any
-fasynchronous-unwind-tables options were already specified.
-fasynchronous-unwind-tables causes a full strack trace to be produced when
the sanitizer detects an error. Without the full trace several of the asan
test cases fail on powerpc.
See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65479 for more information.
Bootstrapped and tested on powerpc64le-unknown-linux-gnu,
powerpc64be-unknown-linux-gnu, and x86_64-pc-linux-gnu with no regressions.
Is this ok for trunk?
