Ard Biesheuvel cdeb268cb0 BaseTools IA32/X64: drop redundant alignment from linker script
There is no need to pad out the end of a section of the start of
the following section is aligned to the same value. So drop the
redundant ALIGN() statements.

Ard Biesheuvel fa1d29d5cc BaseTools IA32/X64: move .rodata to PE/COFF .text section
The .rodata ELF section contains constant non-executable data that
should never be modified by the program itself. Since the risk of
inadvertent modification is typically higher than the risk of
inadvertent execution, it makes sense to put this data in the
R-X .text section rather than in the RW- .data section.
So move it there.

Ard Biesheuvel e90ba6e1ea BaseTools IA32/X64: remove NOP padding from X86/IA32 GCC linker scripts
The NOP padding in the GCC linker scripts ensures that all empty
regions in the ELF binary are filled with x86 NOP instructions.

There is no upside to doing this: if the CPU ends up executing these
instructions, we have little hope of resuming normal execution of the
program anyway. And having NOP slides in memory only makes it easier
for attackers to launch exploits. So remove them.
