Arm Compiler 6 (up to 6.10) compilation dysfunctional

Note: Arm Compiler 6 beginning with 6.10.1 is not affected.

Effect: Compilation will most likely fail with an error message like:

In file included from CMSIS/Core/Include/cmsis_compiler.h:41:
In file included from CMSIS/Core/Include/cmsis_armclang_ltm.h:33:
arm_compat.h:42:1: error: expected identifier or '('
static __inline__ unsigned int __attribute__((__always_inline__, __nodebug__))
^
1 error generated.

Cause: An invalid character made it into cmsis_armclang_ltm.h at beginning of line 1:

^/**************************************************************************//**
 * @file     cmsis_armclang.h
 * @brief    CMSIS compiler armclang (Arm Compiler 6) header file

Work around: Remove the ^ at the beginning of this file.
