Make the arm port build cleanly with Clang.
This fixes the following two warnings, so that "make all" builds cleanly
with Clang:
src/arm/macro-assembler-arm.h:1410:7: error: private field
'instructions_' is not used
[-Werror,-Wunused-private-field]
int instructions_; // Number of instructions of the expected patch size.
^
src/arm/simulator-arm.cc:402:20: error: variable 'words' is used uninitialized whenever 'if'
condition is false [-Werror,-Wsometimes-uninitialized]
} else if (argc == next_arg + 1) {
^~~~~~~~~~~~~~~~~~~~
../src/arm/simulator-arm.cc:407:21: note: uninitialized use occurs here
end = cur + words;
^~~~~
../src/arm/simulator-arm.cc:402:16: note: remove the 'if' if its condition is always true
} else if (argc == next_arg + 1) {
^~~~~~~~~~~~~~~~~~~~~~~~~~
