Zhao Jiazhong 78e40de874 [loong64][mips64][heap/cppgc] Disable guard pages 
Page size is normally 16k on loongarch64 and mips64 platforms, which

Zhao Jiazhong f385232a87 [loong64][mips] Fix safepoint record of CallCFunction 
Currently, the safepoint is last call instruction's return address on
mips and loongarch64 platform. But in `CallCFunction`, there are some
other instructions after calling, which leading to a wrong safepoint
record on mips and loongarch64.

So I record the pc for safepoint at the end of `CallCFunction`
function, and change `last_call_pc_` to `pc_for_safepoint_`.

Besides, commit 48b2b89176 introduced
a typo on loong64 platform, I also fixed it in this CL.
