DSP: Remove undefined behavior in post-increment/decrement read ( #1443 )
...
According to the C standard q15_t * and const q15_t * are not compatible
types which, among other things, imply that an object of type const
q15_t * can't be modified by writing to a q15_t ** or vice versa.
Programs doing this are undefined.
Because of this rule all programs using the functions read_q15x2_ia,
read_q15x2_da, read_q7x4_ia, or read_q7x4_da for reading data from an
array of constant elements will be undefined. To solve this it is not
enough to change the type of the function since this will give problems
when reading data from an array of non-const elements. To get a defined
solution I needed to switch from functions to macros to allow the
increment to be done in the original type of the pointer.

CMSIS-DSP: Improvements to pull request #1363
...
To avoid having to change the API in an incompatible way,
a arm_mat_mult_opt_q31 was introduced and is providing a faster implementation
to use with Helium (but requiring more storage for intermediate results).
Some improvements to tests for matrix functions added.

The IAR compiler appears to provide more warnings about type
mismatches than the other compilers. This cleans a lot of them up.
