[test][LoongArch] Add -mattr=+d option. NFC
Because most of tests assume target-abi=`lp64d`, adding the
corresponding feature is reasonable.

[LoongArch] Support inline asm operand modifier 'z'
Print $zero register if operand is zero, otherwise print it normally.
Clang is highly compatible [1] with GCC inline assembly extensions,
allowing the same set of constraints, modifiers and operands as GCC
inline assembly. This patch tries to make it compatible regarding
LoongArch specific operand modifiers.
GCC supports many modifiers [2], but it seems that only x86 and msp430
are documented [3][4]. I don't know if any other modifiers are being
used except the 'z' in Linux [5].
