Add -malign-data={abi|compat|cachineline} · 239711f6

Add -malign-data={abi|compat,cachineline} to control how GCC aligns
variables.  "compat" uses increased alignment value compatible with
GCC 4.8 and earlier, "abi" uses alignment value as specified by the
psABI, and "cacheline" uses increased alignment value to match the
cache line size.  "compat" is the default.

	* config/i386/i386.c (ix86_data_alignment): Return the ABI

compiler: Don't built hash/equality functions for thunk structs. · e0d475db

They are never necessary, and they can cause problems when a
thunk is used to pass an unexported type from a different
package to a function defined in that package.  The resulting
struct type may need to call the comparison routine from the
other package, which will fail because the type is not
exported.  This will be bug492 in the master testsuite.
