[amd64] use 32bit variant of lea_membase for 32bit operations (#13642)
[amd64] use 32bit variant of lea_membase for 32bit operations
Consider
```
xor %r15, %r15 // %r15 = 0x0
dec %r15d // %r15 = 0xffff_ffff
lea 0x1(%r15), %rdx // %rdx = 0x1_0000_0000 but should be 0x0
```
instead `lea 0x1(%r15), %edx` should be generated.
Fixes #13452
Fixes #13597
