pierre.langlois 11b661f414 [turbofan] ARM: Support shifted indexes in loads and stores 
This patch is a follow up to https://codereview.chromium.org/1972103002/
adding support for the `Operand_R_LSL_I` addressing mode to loads and
stores for ARM.

Just as the ARM64 implementation, the shift + load/store pattern is only
really relevant to the interpreter. For this reason, this patch does not
add support for the other addressing modes (`R_LSR_I`, `R_ASR_I` and
`R_ROR_I`) as I haven't seen those pattern being generated. Additionally,
the optimization is restricted 32 bit loads and stores.
