Summary

[asan Win64] Use multiple trampolines for interception
Due to large address space in x64, it is not safe to assume
a single trampoline area can be reachable within +/-2G of
every one of the intercepted function address. This patch
provides a way to search and allocate a free page from the
end of each image for trampoline usage. Currently it simply
allocates a new page for every interception.
