Adds use of restrict keyword to improve encoding speed.

Restrict works very poorly in Visual Studio (much slower than without)
so defined flac_restrict in share/compat.h and use that in:

    lpc_compute_residual...()
    lpc_restore_signal...()

As a result, FLAC__lpc_compute_residual_from_qlp_coefficients_wide_intrin_sse41()
offers no advantage for 64-bit compiles and was removed from x86-64 part
of stream_encoder.c

Vcproj file updates.

rplaces

with
     OutputDirectory="$(SolutionDir)objs\$(ConfigurationName)\bin
and so on.

Rmoves
     OutputFile="..\..\objs\debug\lib\$(ProjectName).lib
when possible.

Also, in the current version "Whole program optimization" compiler option
is set, but the corresponding linker option isn't. From MSDN:
   "If you do not explicitly specify /LTCG when you pass /GL or MSIL modules
   to the linker, the linker eventually detects this and restarts the link
   by using /LTCG. Explicitly specify /LTCG when you pass /GL and MSIL modules
   to the linker for the fastest possible build performance."
So /LTCG option was added too.

Debug build now uses libogg_static.lib from .\objs\debug\lib folder.
(the dependency for both release and debug is
    objs\$(ConfigurationName)\lib\libogg_static.lib)
