This patch tracks the type of Cmm global registers. This is needed
in order to lint uses of polymorphic registers, such as SIMD vector
registers that can be used both for floating-point and integer values.
This changes allows us to refactor VanillaReg to not store VGcPtr,
as that information is instead stored in the type of the usage of the
register.
Fixes #22297

This reverts commit 3be48877, which weakened a Cmm Lint check involving
SIMD vectors. Now that we keep track of the type a global register is
used at, we can restore the original stronger check.

Currently, the wasm NCG has an implicit assumption: all CmmSwitch
scrutinees are 32-bit integers. This is not always true; #22864 is one
counter-example with a 64-bit scrutinee. This patch fixes the logic by
explicitly converting the scrutinee to a word that can be used as a
br_table operand. Fixes #22871. Also includes a regression test.
