[PATCH] gcc/reload.h: Change type of x_spill_indirect_levels

[Eddy Young]

This patch changes the type of `x_spill_indirect_levels` member of
`struct target reload` from `bool` to `unsigned char`.

Without this change, the build of esp-open-sdk fails with GCC 11 and
above.

(Please bear with me, this is my first patch submission.)

        Cheers,
        Eddy
