[AArch64][TLSLE][2/3] Add the option "-mtls-size" for AArch64

[Jiong Wang <jiong.wang@arm.com>]

[-- Attachment #1: Type: text/plain, Size: 710 bytes --]


As we have added -mtls-size support, there should be four types TLSLE
symbols:

  SYMBOL_TLSLE12
  SYMBOL_TLSLE24
  SYMBOL_TLSLE32
  SYMBOL_TLSLE48

which reflect the maximum address bits needed to address this symbol.

This patch rename SYMBOL_TLSLE to SYMBOL_TLSLE24. Patch [3/3] will add
support for other symbol types.

OK for trunk?

  * config/aarch64/aarch64-protos.h (aarch64_symbol_type): Rename
  SYMBOL_TLSLE to SYMBOL_TLSLE24.
  * config/aarch64/aarch64.c (aarch64_load_symref_appropriately): Likewise
  (aarch64_expand_mov_immediate): Likewise
  (aarch64_print_operand): Likewise
  (aarch64_classify_symbol): Likewise
