target-arm: optimize thumb 32-bit multiply

Current implementation of thumb mul instruction is implemented as a
32x32->64 multiply which then uses only 32 least significant bits of
the result. Replace that with a simple 32x32->32 multiply.

target-arm: cleanup internal resource leaks

Revised patch for getting rid of tcg temporary variable leaks in
target-arm/translate.c. This version also includes the leak patch for
gen_set_cpsr macro, now converted as a static inline function, which I
sent earlier as a separate patch on top of this patch....

target-arm: fix sdiv helper

(INT32_MIN / -1) triggers an overflow, and the result depends on the
host architecture (INT32_MIN on arm, -1 on ppc, SIGFPE on x86). Use a
test to output the correct value.

target-arm: fix bugs introduced by 1b2b1e547bd912b7d3c4863d0a0f75f6f38330ed

Use load_reg_var() instead of accessing cpu_R[rn] directly to generate
correct code when rn = 15.
