gdb: Have allocate_target_description return a unique_ptr
There were a few places where we could (should?) have delayed
releasing the target_desc_up until a little later. This commit
catches these cases.
In the case of ARC, the target_desc_up is now exposed right out to
gdbserver, which means making a small change there too.
There should be no user visible changes after this commit.
gdb/ChangeLog:
* arch/aarch32.c (aarch32_create_target_description): Release the
target_desc_up as late as possible.
* arch/aarch64.c (aarch64_create_target_description): Likewise.
* arch/amd64.c (amd64_create_target_description): Likewise.
* arch/arc.c (arc_create_target_description): Return a
target_desc_up, don't release it.
* arch/arc.h (arc_create_target_description): Update declaration.
(arc_lookup_target_description): Move target_desc_up into the
cache, and return a borrowed pointer.
* arch/arm.c (arm_create_target_description): Release the
target_desc_up as late as possible.
* arch/i386.c (i386_create_target_description): Likewise.
* arch/riscv.h (riscv_create_target_description): Update
declaration to match definition.
* arch/tic6x.c (tic6x_create_target_description): Release the
target_desc_up as late as possible.
gdbserver/ChangeLog:
* linux-arc-low.cc (arc_linux_read_description): Release the
unique_ptr returned from arc_create_target_description.
