arm.md (tablejump): Make this a define_expand.
* arm.md (tablejump): Make this a define_expand. For PIC add the
offset to the base of the table.
(thumb_tablejump): Matcher for Thumb tablejump insn.
* config/arm/aout.h (ASM_OUTPUT_ADDR_DIFF_ELT): Output thumb entries
as the difference of two labels.
* config/arm/aof.h (ASM_OUTPUT_ADDR_DIFF_ELT): Likewise.
* config/arm/elf.h (JUMP_TABLES_IN_TEXT_SECTION): Only put ARM jump
tables in the code.
* config/arm/coff.h (JUMP_TABLES_IN_TEXT_SECTION): Likewise.
* arm.c (get_jump_table_size): If the table is not in the text
section, return zero.
