amdgcn: additional gfx1030/gfx1100 support
This is enough to get gfx1030 and gfx1100 working; there are still some test
failures to investigate, and probably some tuning to do.
gcc/ChangeLog:
* config/gcn/gcn-opts.h (TARGET_PACKED_WORK_ITEMS): Add TARGET_RDNA3.
* config/gcn/gcn-valu.md (all_convert): New iterator.
(<convop><V_INT_1REG_ALT:mode><V_INT_1REG:mode>2<exec>): New
define_expand, and rename the old one to ...
(*<convop><V_INT_1REG_ALT:mode><V_INT_1REG:mode>_sdwa<exec>): ... this.
(extend<V_INT_1REG_ALT:mode><V_INT_1REG:mode>2<exec>): Likewise, to ...
(extend<V_INT_1REG_ALT:mode><V_INT_1REG:mode>_sdwa<exec>): .. this.
(*<convop><V_INT_1REG_ALT:mode><V_INT_1REG:mode>_shift<exec>): New.
* config/gcn/gcn.cc (gcn_global_address_p): Use "offsetbits" correctly.
(gcn_hsa_declare_function_name): Update the vgpr counting for gfx1100.
* config/gcn/gcn.md (<u>mulhisi3): Disable on RDNA3.
(<u>mulqihi3_scalar): Likewise.
libgcc/ChangeLog:
* config/gcn/amdgcn_veclib.h (CDNA3_PLUS): Handle RDNA3.
libgomp/ChangeLog:
* config/gcn/time.c (RTC_TICKS): Configure RDNA3.
(omp_get_wtime): Add RDNA3-compatible variant.
* plugin/plugin-gcn.c (max_isa_vgprs): Tune for gfx1030 and gfx1100.
