[patch] PR54645 move location_adhoc_data map into GC

[Dehao Chen <dehao at google dot com>]

Hi,

This patch moves location_adhoc_data into GC, and also rebuild the
hash table when reading in the PCH. After the patch, PCH can work as
expected.

Bootstrapped and passed gcc regression tests on x8664_linux.

OK for trunk?

Thanks,
Dehao
