[AARCH64] Add scheduler for ThunderX

This adds the schedule model for ThunderX. There are a few TODOs in that
not all of the SIMD is model currently.  Also the idea of a simple
shift/extend is not modeled and all cases where there is a shift/extend
is considered as non simple and take up two cycles rather than correct
value of one cycle.  Also the 32bit divide and the 64bit divide
have different cycle counts but there is no way to model that currently.
Also multiply high takes one cycle more than the normal multiply but
there is no way to model that currently either.

Build and tested for aarch64-elf with no regressions.

ChangeLog:
* config/aarch64/aarch64-cores.def (thunderx): Change the scheduler
over to thunderx.
* config/aarch64/aarch64.md: Include thunderx.md.
(generic_sched): Set to no for thunderx.
* config/aarch64/thunderx.md: New file.

Daily bump.

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@217456 138bc75d-0d04-0410-961f-82ee72b054a4

compiler: Do not count package uses from ambiguous lookups.

When using dot imports, it is possible to
have an imported symbol name that matches
the name of a struct field in a composite
literal.  Do not consider the imported
package to be used in this situation.
Fixes issue 6427.
