Paolo Bonzini 63c915526d cpu: move exec-all.h inclusion out of cpu.h
exec-all.h contains TCG-specific definitions.  It is not needed outside
TCG-specific files such as translate.c, exec.c or *helper.c.

One generic function had snuck into include/exec/exec-all.h; move it to
include/qom/cpu.h.

Richard Henderson 112e4518f0 target-alpha: Special case cmpbge with zero
Knowing the comparator is zero leads to a simpler operation.

Richard Henderson 5f2a80adc6 target-alpha: Rewrite helper_cmpbge using bit tests
Not quite as good as using a proper host vector compare,
but certainly better than a loop.

Peter Maydell f5790c3bc8 Revert "target-alpha: Add vector implementation for CMPBGE"
This reverts commit 32ad48abd7.

Unfortunately the SSE2 code here fails to compile on some versions
of gcc:
 target-alpha/int_helper.c:77:24: error: invalid operands to binary >=
 (have '__vector(16) unsigned char' and '__vector(16) unsigned char')

Richard Henderson 32ad48abd7 target-alpha: Add vector implementation for CMPBGE
While conditionalized on SSE2, it's a "portable" gcc generic vector
implementation, which could be enabled on other hosts.

Richard Henderson 4d1628e832 target-alpha: Fix integer overflow checking insns
We need to write the result to the destination register before
raising any exception.  Thus inline the code for each insn, and
check for any exception after we're done.

Richard Henderson 2ef6175aa7 tcg: Invert the inclusion of helper.h
Rather than include helper.h with N values of GEN_HELPER, include a
secondary file that sets up the macros to include helper.h.  This
minimizes the files that must be rebuilt when changing the macros
for file N.
