[WebAssembly] Fold sign-extending shifts into signed loads in FastISel (#185906) 
WebAssembly FastISel currently fails to fold sign-extension patterns
composed of zero-extending loads followed by shift operations. This
results in redundant shift and constant instructions in the output.

Before:
  i32.load8_u $push3=, 0($0)
  i32.const $push0=, 24
  i32.shl $push1=, $pop3, $pop0
  i32.const $push4=, 24
  i32.shr_s $push2=, $pop1, $pop4

The matched shift instruction sequence is removed and safely folded into
a single sign-extending load, erasing the dead code via the
MachineBasicBlock iterator.

After:
  i32.load8_s $push0=, 0($0)

Fixed: #184302
