53546ce0b6 Update listing of when SSSE3 and SSE4.1 first became available
SSSE3 was first available on the original Intel Core 2 processors, so
add the "Merom" codename. SSE4.1 was available on the 45 nm shrink of
those processors, codename "Penryn", not on the next architecture.

735f7e6248 Record the sub-architecture (CPU features enabled in the compiler)
If the system's compiler has extra features on top of the base
settings enabled or if the mkspec or $CXXFLAGS variable included some,
record them.

This will allow us to choose whether or not to use our own special
compilers, based on whether the system default compiler contains it or
not.

1533bfc5fc Improve the architecture-detection mechanism
For the Unix part, this now obeys the -v option, printing the full
command-line it used to compile, allowing testers to identify why
something went wrong.

Unfortunately, it requires a full compilation cycle, instead of just
preprocessing. Just one more among the many on Unix, but maybe a
noticeable slow-down on Windows.

fcec903da7 Ensure that qXXXdetection.h can be included directly
Those files might have dependency on one another, on qconfig.h and on
early qglobal.h definitions, so ensure that the only correct include
order is that of qglobal.h.

4cc9523a31 Make architecture detection more robust.
Any message/error in mkspecs or qmake feature files ends up confusing
the current arch detection logic. Instead, search for
"Project MESSAGE: .* Architecture: <arch>".

d4959fa637 arch: Undefine possible architecture defines
Some compilers define the architecture to one leading to detecting
'1' as target architecture. Always undef the architecture name.

Compilers:
gcc version 4.6.3 (Debian 4.6.3-1) has '#define i386 1'
gcc version 4.5.3 (Broadcom stbgcc-4.5.3-1.3) has '#define mips 1'

ba6952b28d Remove -arch argument and #define QT_ARCH from configures
Do not try to detect the host or target architectures using uname or
similar, and do not override with the -arch or -host-arch configure
arguments. The configures will still accept the -arch and -host-arch
arguments, but it ignores them and instead outputs a warning stating
that these arguments are obsolete and should not be used.

Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler
target. This is done by running qmake (twice when cross-compiling) on
config.tests/arch/arch.pro, which preprocesses a file that contains all
knowns processors.

On Windows, configure.exe has never run any config.tests before, and
does not currently have a function to run a program and capture its
output. Use _popen() to accomplish this (as qmake does for its system()
function). This needs to be done after qmake is built, as does the
mkspecs/qconfig.pri generation. As a side effect, the configure steps
have been slightly re-ordered, but the overall result is the same. The
displayConfig() call is moved to just before generating Makefiles, so
that it can show the detected architecture(s).
