Determine HLoadClass/String load kind early.

This helps save memory by avoiding the allocation of
HEnvironment and related objects for AOT references to
boot image strings and classes (kBootImage* load kinds)
and also for JIT references (kJitTableAddress).

Compiling aosp_taimen-userdebug boot image, the most memory
hungry method BatteryStats.dumpLocked() needs
  - before:
    Used 55105384 bytes of arena memory...
    ...
    UseListNode    10009704
    Environment      423248
    EnvVRegs       20676560
    ...
  - after:
    Used 50559176 bytes of arena memory...
    ...
    UseListNode     8568936
    Environment      365680
    EnvVRegs       17628704
    ...
