target-alpha: Fix cvtlq.
We were missing the 0xc0000000 mask, leading to incorrect results.

target-alpha: Fix float32_to_s vs zero exponent.
There was a bug in float32_to_s that incorrectly mapped a zero exponentto 0x38. This meant 0.0f != 0. At the same time, fix a generic typepunning bug in helper_memory_to_s and helper_s_to_memory.

target-alpha: Implement fp branch/cmov inline.
The old fcmov implementation had a typo:- tcg_gen_mov_i64(cpu_fir[rc], cpu_fir[ra]);which moved the condition, not the second source, to the destination.
But it's also easy to implement the simplified fp comparison inline....
target-alpha: Expand ins*l inline.
Similar in difficulty to ext*l, already expanded.
target-alpha: Expand msk*l inline.
target-alpha: Expand msk*h inline.
target-alpha: Expand ins*h inline.
target-alpha: Implement missing MVI instructions.
target-alpha: Remove bogus DO_TB_FLUSH code from translator.
target-alpha: Fixes for alpha-linux syscalls.
1. Add correct definitions of error numbers.2. Implement SYS_osf_sigprocmask3. Implement SYS_osf_get/setsysinfo for IEEE_FP_CONTROL.
This last requires exposing the FPCR value to do_syscall.Since this value is actually split up into the float_status,...
Revert "Get rid of _t suffix"
In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Somethinglike this must be presented on the list first so people can provide input...
Get rid of _t suffix
Some not so obvious bits, slirp and Xen were left alone for the timebeing.

Replace always_inline with inline
We define inline as always_inline.
Update to a hopefully more future proof FSF address
target-alpha: remove amask helper
The direct use of helper_amask in translate.c was bogus (as env is notassigned). Directly code amask in tcg and remove the helper.

target-alpha: remove helper_load_implver
There is no need to use an helper. Directly load the value with tcg code.

target-alpha: overflow condition for sublv and subqv
The conditions to detect overflow in sub operations was wrong.
This patch is necessary to boot Tru64.
target-alpha: tb_flush helper should flush the tb (and not the tlb).
Looks to be a typo fix.
