gold: Update GNU_PROPERTY_X86_XXX macros

This patch updates GNU_PROPERTY_X86_XXX macros for gold:

1. GNU_PROPERTY_X86_UINT32_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_AND_LO      0xc0000002
 #define GNU_PROPERTY_X86_UINT32_AND_HI      0xc0007fff

2. GNU_PROPERTY_X86_UINT32_OR_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_LO    0xc0008000
 #define GNU_PROPERTY_X86_UINT32_OR_HI    0xc000ffff

3. GNU_PROPERTY_X86_UINT32_OR_AND_XXX: A 4-byte unsigned integer property.
A bit is set if it is set in any relocatable inputs and the property is
present in all relocatable inputs:

 #define GNU_PROPERTY_X86_UINT32_OR_AND_LO   0xc0010000
 #define GNU_PROPERTY_X86_UINT32_OR_AND_HI   0xc0017fff

4. GNU_PROPERTY_X86_FEATURE_2_NEEDED, GNU_PROPERTY_X86_FEATURE_2_USED
and GNU_PROPERTY_X86_FEATURE_2_XXX bits.

GNU_PROPERTY_X86_FEATURE_1_AND is unchanged.  GNU_PROPERTY_X86_ISA_1_USED
and GNU_PROPERTY_X86_ISA_1_NEEDED are updated to better support targeted
processors since GNU_PROPERTY_X86_ISA_1_?86 aren't isn't very useful.
A new set of GNU_PROPERTY_X86_ISA_1_XXX bits are defined.  The previous
GNU_PROPERTY_X86_ISA_1_XXX macros are deprecated and renamed to
GNU_PROPERTY_X86_COMPAT_ISA_1_XXX and GNU_PROPERTY_X86_COMPAT_2_ISA_1_XXX.
