[ARM] Allow execute only code on Cortex-m23
The NoMovt feature prevents the use of MOVW/MOVT instructions on Cortex-M23 for performance reasons. These instructions are required for execute only code so NoMovt should be disabled when that option is enabled. Differential Revision: https://reviews.llvm.org/D52551 llvm-svn: 343302
