According to Agner Fog, "...you must make sure that all calls
are matched with returns. Never jump out of a subroutine without
a return and never use a return as an indirect jump."
(see paragraph 3.15 in microarchitecture.pdf and
examples 3.5a and 3.5b in optimizing_assembly.pdf)

Most non-static functions have FLAC__ prefix, but they were missing
from the precompute_partition_info_sums_* functions.

Besides SPE (FSL e500v? cores) there are other powerpc processors
that don't support altivec instructions so only enable them when it's
100% sure that the target has it.

Autoconf detects the Clang compiler as GNU GCC (clang sets defines like
__GNUC__ etc) but Clang is *not* completely compatible. If we detect
Clang we set ac_vc_c_compiler_gnu to 'no'.
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

rplaces
OutputDirectory="..\..\..\..\objs\debug\bin"
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)

* Splits lpc_x86intrin.c to lpc_intrin_sse.c and lpc_intrin_sse2.c
* Add FLAC__lpc_compute_residual_from_qlp_coefficients_intrin_sse2()
function to lpc_intrin_sse2.c
* Add lpc_intrin_sse41.c with two ..._wide_intrin_sse41() functions
(useful for 24-bit en-/decoding)
* Add precompute_partition_info_sums_intrin_sse2() / ...ssse3() and
disables precompute_partition_info_sums_32bit_asm_ia32_().
SSE2 version uses 4 SSE2 instructions instead of 1 SSSE3 instruction
PABSD so it is slightly slower.

For some reason all documentation lists the max rice partition
order to be 16, while the maximum is 15. This fixes flac -H, the
man page and the HTML source code documentation

Before this patch it was possible to set or get data.ia32.sse3 value
from x86-64 code, etc which is a potential source of errors.

While developing FLAC Frontend, there where several occasions where
I felt little restrained because the FLAC logo is available only in
gif. I made an SVG version and rendered a new GIF version from it.

A preprocessor macro FLAC__ALIGN_MALLOC_DATA is defined in the Makefiles
but absent in *.vcproj files. This patch adds it to libFLAC_static.vcproj
and libFLAC_dynamic.vcproj.

For the 32 bit x86 ASM functions there were already versions of this
function for lags (N = 4, 8, 12). They require lpc_order less than N.
The best compression preset (flac -8) uses lpc_order up to 12; it
means that during encoding FLAC also uses unaccelerated C function.

When compiling for ia32 on an x86_64 kernel, the configure script
was not detecting the ability to do asm optimisations because the
configure script was detecting the x86_64 kernel not the ia32
user space.
The AWK script used to generate tones for this test fails with gawk
version 4.0.1, but used to work for earlier versions. Use mawk instead
if it exists.
