fix dump file issue
Use -DPREFIX instead of --prefix _ on OS X

The --prefix parameter differs between yasm and nasm; nasm
requires --prefix _ while yasm requires --prefix=_. Using the
define instead (as on windows) allows easier switching between
the two otherwise mostly compatible assemblers.

This fixes building with yasm on OS X in 32 bit mode. For 64 bit,
a few more tweaks are still required.
Indent all WELS_ASM_FUNC_BEGIN properly

By having all of them start at the start of the line, the code
is more consistent and readable.

Indent all WELS_ASM_FUNC_BEGIN properly
Use the SIGN_EXTENSION macro where possible

This shortens the x86 assembly by 134 lines in total.
Remove the unused FORMAT_COFF define

Nothing in the project currently sets FORMAT_COFF - the other generic
branch works just fine on windows.
