ash: eval: Reset handler when entering a subshell

Apply upstream commit 81274d8b3.

On Windows it isn't necessary to reset the exception handler in
evalbackcmd() or evalpipe(), as that will have been done by
forkshell_init().

The globals_misc structure now contains a setjmp() buffer.  On
64-bit Windows this needs 16-byte alignment.  This is achieved
in the forkshell data structure by placing the globals_misc
data immediately after the 16-byte aligned forkshell data.

Saves 144 bytes in the 64-bit build.
