target-arm: Use lookup table for size check on Neon 3-reg-same insns

Simplify the checks for invalid size values for the Neon "three registers
of the same size" instruction forms (and add them where they were missing)
by using a lookup table.

This includes adding symbolic constants for the op values in this space,...

target-arm: Handle UNDEF cases for Neon 3-regs-same insns

Correct the handling of UNDEF cases for the NEON "3 registers same
size" forms, by adding missing checks and rationalising some others
so they are done early enough to avoid leaking TCG temporaries....

target-arm: Simplify three-register pairwise code

Since we know that the case of (pairwise && q) has been caught
earlier, we can simplify the register setup code for each pass
in the three-register-same-size Neon loop.

target-arm: Handle UNDEF cases for Neon "2 regs and shift" insns

Correctly handle all the UNDEF cases for Neon instructions of the
"2 registers and shift" form, and make sure that we check for these
cases early enough not to leak TCG temporaries.

arm: basic support for ARMv4/ARMv4T emulation

Currently target-arm/ assumes at least ARMv5 core. Add support for
handling also ARMv4/ARMv4T. This changes the following instructions:

BX

BKPT, BLX, CDP2, CLZ, LDC2, LDRD, MCRR, MCRR2, MRRC, MCRR, MRC2, MRRC,...

Fix conversions from pointer to tcg_target_long

tcg_gen_exit_tb takes a parameter of type tcg_target_long,
so the type casts of pointer to long should be replaced by
type casts of pointer to tcg_target_long (suggested by Blue Swirl).

These changes are needed for build environments where...

target-arm: Use global env in iwmmxt_helper.c helpers

Use the global 'env' variable in the helper functions in iwmmxt_helper.c.
This means we don't need to pass env as an argument to them any more.

target-arm: Make Neon helper routines use correct FP status

Make the Neon helper routines use the correct FP status from
the CPUEnv rather than using a dummy static one. This means
they will correctly handle denormals and NaNs and will set
FPSCR exception bits properly....

target-arm/helper.c: For float-int conversion helpers pass ints as ints

Correct the argument and return types for the float<->int conversion helper
functions so that integer arguments and return values are declared as
uint32_t/uint64_t, not float32/float64. This allows us to remove the...
