The TCG ARM backends uses integer values to refer to both immediate
values and register number. This makes the code difficult to read.
The patch below replaces all (if I haven't miss any ;-) integer values
representing register number by TCG_REG_* enum values.

Instead of writing very compact code, declare all registers that are
clobbered or reserved one by one. This makes the code easier to read.
Also declare all the 16 registers to TCG, and mark pc as reserved.

There is no need to save the LR register (r14) before a call to a
subroutine. According to the "Procedure Call Standard for the ARM
Architecture", it is the job of the callee to save this register.
Moreover, this register is already saved in the prologue/epilogue.
This patch removes the disabled SAVE_LR code, as there is no need to
reenable later.

Currently when using the change command to switch the file in the cd drive
the command doesn't complain if the file doesn't exit or can't be opened
and the drive keeps the existing image. This patch adds a qerror_report
call to print a message out indicating the failure. This error message
can be used to catch failures.
Current behavior:
