Martins MozeikoandNikita a13afb441e fixes issues with minidump on win32 
minidump did not have proper exception record passed in, so it did not
contain actual issue of the unhandled exception. Also stack walking
before was mutating registers in exception CONTEXT, this means that
minidump did not have proper call stack anymore. Now code make a local
copy of CONTEXT for stack walking.

Martins MozeikoandNikita f330bde8aa better callstack for null calls 
This improves callstack in win32 unhandled exception handler when
indirect call to NULL happens. Before no call stack was printed at
all, so it was hard to know what happened. Now call stack explicitly
will print out [NULL] stack entry + rest of call stack entries. This
is done by manually looking up return address from call stack when
possible.

Also fixes wine compatibility for os_commit function. Wine does not
support RIO buffer functions.

Nikita Smith d1b055c62f Ignore S_REGREL32 during conversion of optimized procedures. 
In optimized builds, MSVC emits parameters as both S_LOCAL and S_REGREL32.
Most likely because their debugger relies on S_REGREL32 to format
parameters in the call stack window.
