i386: Fix gcc.target/i386/pr101716.c (and some related cleanups)

Fix pr101716.c testcase scan-assembler failure.  The combine pass will not
combine instructions that use registers in TARGET_CLASS_LIKELY_SPILLED
class, such as %eax return register in AREG class.

Change the testcase to use pseudos only and explicitly scan for
zero_extendsidi pattern name.

While looking there, also clean ix86_decompose_address a bit: eliminate
common code and use UINTVAL and HOST_WIDE_INT_UC macros in the condition
for AND wrapped address.

gcc/ChangeLog:

	* config/i386/i386.cc (ix86_decompose_address): Eliminate
	common code and use use UINTVAL and HOST_WIDE_INT_UC macros
	in the condition for AND wrapped address.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr101716.c (dg-options): Add -dp.
	(dg-final): Scan for zero_extendsidi.
	(sample1): Change the code to use pseudos only.
