target-arm: Don't use TCGv when we mean TCGv_i32

TCGv changes size depending on the compile time value of
TARGET_LONG_BITS.  This is useful for generating code for MIPS style
"instructions are the same but the register width changes" CPUs, and
also for the generic bits of QEMU which operate on "width of a
virtual address" values, but mostly in the ARM target code we were
using it purely as a shorthand for "any 32 bit value".

This needs to change in preparation for AArch64 support, since an
AArch64-capable v8 core will have 64 bit virtual addresses but still
use 32 bit values for the 32 bit instruction set.

This patch mechanically converts all the occurrences of TCGv,
tcg_temp_new(), tcg_temp_free(), tcg_temp_local_new() and
TCGV_UNUSED() to their explicitly 32 bit counterparts.  This is
correct for everything except the arguments to tcg_gen_qemu_{ld,st}*,
which really do need to be TCGv and so will require a 32-to-64
conversion when building the 32 bit code for AArch64.  Those changes
will be in a separate patch for easier review.

target-arm: Remove gen_ld64() and gen_st64()

gen_ld64() and gen_st64() are used only in one place, so just
expand them out.

Remove Sun4c, Sun4d and a few CPUs

Sun4c and Sun4d architectures and related CPUs are not fully implemented
(especially Sun4c MMU) and there has been no interest for them.

Likewise, a few CPUs (Cypress, Ross etc) are only half implemented.

Remove the machines and CPUs, they can be re-added if needed later.
