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.
