Alex Bennée	35e3f029a9	semihosting/arm-compat-semi: don't use SET_ARG to report SYS_HEAPINFO ... As per the spec: the PARAMETER REGISTER contains the address of a pointer to a four-field data block. So we need to follow arg0 and place the results of SYS_HEAPINFO there.

Alex Bennée	3960ca5b3e	semihosting/arm-compat-semi: unify GET/SET_ARG helpers ... >>>From the semihosting point of view what we want to know is the current mode of the processor. Unify this into a single helper and allow us to use the same GET/SET_ARG helpers for the rest of the code. Having the helper will also be useful later. Note: we aren't currently testing riscv32 due to missing toolchain for check-tcg tests.

Philippe Mathieu-Daudé	8df9f0c3d7	semihosting: Move hw/semihosting/ -> semihosting/ ... With the exception of hw/core/, the hw/ directory only contains device models used in system emulation. Semihosting is also used by user emulation. As a generic feature, move it out of hw/ directory.
