Remove Unnecessary/Erroneous Reads In sgemm_tcopy_16.S COPY1x8 Macro
...
There appears to have been some code leak when copying from the COPY2x8
macro above where we're reading 8 bytes into d4-d7 directly after
reading 4 bytes into s4-s7. These 32 bytes in d4-7 are unused and can
possibly overrun the boundary of allocated memory -- Valgrind detected
this which is what dragged my attention to it for a 128,1 copy.
Additionally, there is no need to update the addresses stored in A0-A7
as the only possible paths after running this macro will overwrite A0-7
if looping to the next 8 rows, or overwrite A0-3 if moving to 4 rows --
in which case A4-7 are unused.

The LLVM and GCC teams agreed to rename the __builtin_mma_assemble_pair and
__builtin_mma_disassemble_pair built-ins to __builtin_vsx_assemble_pair and
__builtin_vsx_disassemble_pair respectively. This patch is to make
corresponding changes in dgemm kernel. Also made changes in
inputs to those builtins to avoid some potential typecasting issues.

Fix building "generic" TRMM kernel with CMake

The CMake "TARGET_CORE" variables stores the "generic" target name in all lowercase letters, but gets compared to an all uppercase string, which results in the wrong TRMM kernel being selected.
This commit converts the TARGET_CORE to all uppercase before comparing its value to make sure case mismatches are not an issue in the future anymore.
