Otherwise, it's possible for the old handle to be re-added to the cache between
removing and closing it.

If another thread creates and accesses a file between the dup_handle request and
the call to remove_fd_from_cache(), the file may be allocated to the same handle
number, and that thread will then receive the wrong unix fd. Avoid this race by
invalidating the cache first.

WoW64 process has two separate contexts:
- x86 context used most of the time (e.g. by application code)
- x86_64 context used by system when it quits x86 emulation and jumps to
the kernel code
A notable exception are debug registers - their state is shared. Some
debuggers make use of that fact and sets/gets debug registers of x86
processes using x86_64 thread context.
Add support for setting and getting debug registers using x86_64
thread context. Getting other registers is allowed too and will return
values from x86 thread context.
Fixes hardware breakpoints in IDA 7.0 disassembler (x86_64 app) when
debugging x86 (32 bit) applications.
