target-alpha: fix emulation of ecb

As ECB is a hint, it can be safely emulated as a nop.

This change is necessary to boot Tru64.

target-alpha: remove amask helper

The direct use of helper_amask in translate.c was bogus (as env is not
assigned). Directly code amask in tcg and remove the helper.

Add new command line option -singlestep for tcg single stepping.

This replaces a compile time option for some targets and adds
this feature to targets which did not have a compile time option.

Add monitor command to enable or disable single step mode.

Modify monitor command "info status" to display single step mode....

target-alpha: bug fix: avoid nop to override next instruction

While searching PC, always store the pc of a new instruction.
Instructions that didn't generate tcg code (such as nop) prevented the next
one to be referenced.
