* config/arm/arm.h (CASE_VECTOR_PC_RELATIVE): Remove arm targets
from (!target_pure_code) condition.
(ADDR_VEC_ALIGN): Add align for tables in rodata section.
* config/arm/arm.cc (arm_output_casesi): Alter the function to include
.Lrtx label and remove adr instructions.
* config/arm/arm.md
(arm_casesi_internal): Use force_reg to generate ldr instructions that
would otherwise be out of range, and change rtl to accommodate force
reg.
Additionally remove unnecessary register temp.

* config/arm/elf.h (JUMP_TABLES_IN_TEXT_SECTION): Remove arm
targets from JUMP_TABLES_IN_TEXT_SECTION definition.
