[ARM] Fix Coprocessor instructions availability

Browse Source 
A few coprocessor instructions introduced in ARMv2 are currently
accepted by GAS when targeting ARMv1 due to a typo in the code. This
patch fixes the issue and introduce a more fine grained testing for
coprocessor instructions availability. Coprocessor instructions are
grouped as follows:

* ARM coprocessor instructions introduced in ARMv2
  Includes: ldc, stc, mcr, mrc, cdp, ldcl, stcl
  Guarded by: ARM_EXT_V2
  Tests: copro-arm_v2plus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv5
  Includes: ldc2, ldc2l, stc2, stc2l, cdp2, mcr2, mrc2
  Guarded by: ARM_EXT_V5
  Tests: copro-arm_v5plus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv5TE
  Includes: mcrr, mrrc
  Guarded by: ARM_EXT_V5E
  Tests: copro-arm_v5teplus-arm_v*.d

* ARM coprocessor instructions introduced in ARMv6
  Includes: mcrr2, mrrc2
  Guarded by: ARM_EXT_V6
  Tests: copro-arm_v6plus-arm_v*.d

* Thumb coprocessor instructions introduced in ARMv6T2
  Includes: ldc, ldcl, stc, stcl, mcr, mrc, mcrr, mrrc, cdp, ldc2,
  ldc2l, stc2, stc2l, cdp2, mcr2, mrc2, mcrr2, mrrc2
  Guarded by: ARM_EXT_V6T2
  Tests: copro-thumb_v6t2plus-thumb_v*.d

For each of these groups, at least 2 tests are performed:
* instructions are not available in earlier architecture
* instructions are available in architecture where they were introduced
More tests need to be performed when instructions in a group span
several assembly files.

Note that an instruction in the original coprocessor testcase is
changed to unified syntax to allow the testcase to be assembled for ARM
and Thumb state. Correct processing of legacy syntax is covered in other
testcases.
