[PATCH] tests/tcg/hexagon: fix underspecifed asm constraints

[Mukilan Thiyagarajan]

There are two test cases where the inline asm doesn't
have the correct constraints causing them to fail when
using certain clang versions/optimization levels.

In mem_noshuf.c, the register r7 is written to but
not specified in the clobber list.

In misc.c, the 'result' output needs the early clobber
modifier since the rest of the inputs are read after
assignment to the output register.
