[RFA/ARM] Fix bug with handling of BKPT and IT blocks.

[Matthew Gretton-Dann]

All,

The attached patch fixes a bug in gas with respect to its handling of BKPT 
instructions inside IT blocks.

BKPT instructions are always unconditional even inside an IT block.

Gas correctly handles this when an immediate is specified for the BKPT 
instruction, but does not when the immediate is omitted.

OK?

gas/ChangeLog:
2012-06-06  Matthew Gretton-Dann  <matthew.gretton-dann@arm.com>

	* config/tc-arm.c (do_t_bkpt): Handle IT state even if there is
	no argument.

gas/testsuite/ChangeLog:
2012-06-06  Matthew Gretton-Dann  <matthew.gretton-dann@arm.com>

	* gas/arm/thumb2_bcond.d: Test bkpt with no arguments.
	* gas/arm/thumb2_bcond.s: Likewise.

Thanks,

Matt
