[Gcc4cli-devel] CLI-BE (rev 170127): more functionality in libstd::stat()

[David Y. <dav...@in...>]

This patch (committed as revision 170127) provides more functionality to libstd::stat. New fields in 'struct stat' have been added. 

New core functions: file_lastaccess_sutc, file_lastwrite_sutc, file_filecreation_sutc, file_mode_flags, 
file_uid, file_gid 

Implementation in MSCorelibWrapper (-> MSCorelibWrapper.dll): 
file_filecreation_sutc() tries to behave as 'struct stat::st_ctime', but it is not exactly the same. 
st_ctime is the time of the last change of status (mode, owner, etc.), while file_filecreation_sutc() 
returns creation time. This difference arises from .NET design. 
file_mode_flags() is only a partial approximation. I did my best with the permits in .NET, but there is 
not a perfect match. 
file_uid() and file_gid() returns 0 

Implementation in __host.c (-> optimized MSCorelibWrapper.dll, libstd.so): 
Each core function uses a call to the host 'stat()' in order to get the requested value 
(may be some kind of caching implementation could improve this) 

Affected benchmarks: 164.gzip
