  ldexp: fix INT_MIN infloop
  
  * lib/ldexp.c (FUNC): Instead of converting EXP to unsigned,
  work on it directly.  This simplifies the code and avoids
  an infinite loop when EXP == INT_MIN.
  * modules/ldexp, modules/ldexpl: Depend on stdbool.
  * tests/test-ldexp.h: Include <limits.h> for INT_MIN.
  (test_function): Test for infloop.
