Christophe Monat 9239bbd3a6 [ARM/STM32L4XX] PR 20030: --fix-stm32l4xx-629360 fails to create vldm/vpop veneers for double-precision registers
bfd/
	PR ld/20030
	* elf32-arm.c (is_thumb2_vldm): Account for T1 (DP) encoding.
	(stm32l4xx_need_create_replacing_stub): Rename ambiguous nb_regs
	to nb_words.
	(create_instruction_vldmia): Add is_dp to disambiguate SP/DP
	encoding.
	(create_instruction_vldmdb): Likewise.
	(stm32l4xx_create_replacing_stub_vldm): is_dp detects DP encoding,
	uses it to re-encode.

ld/
	PR ld/20030
	* testsuite/ld-arm/arm-elf.exp: Run new stm32l4xx-fix-vldm-dp
	tests. Fix misnamed stm32l4xx-fix-all.
	* testsuite/ld-arm/stm32l4xx-fix-vldm-dp.s: New tests for multiple
	loads with DP registers.
	* testsuite/ld-arm/stm32l4xx-fix-vldm-dp.d: New reference file.
	* testsuite/ld-arm/stm32l4xx-fix-vldm.s: Add missing comment.
	* testsuite/ld-arm/stm32l4xx-fix-all.s: Add tests for multiple
	loads with DP registers.
