[PATCH 0/5] [asan] Update libsanitizer for x32

[H.J. Lu]

Hi,

libsanitizer is also used by GCC which supports x32.  X32 uses ILP32
data model on Linux/x86-64.  I am submitting 5 patches to update
libsanitizer for x32.

H.J. Lu (5):
  Use 64-bit pointer to unwind stack for x86-64
  Use 64-bit ints in linux_dirent for Linux/x86-64
  Cast pointers to uptr when calling internal_syscall
  Set thread descriptor size to 1728 for x32
  Avoid shift count overflow in CanBeAHeapPointer
