NASM has replaced ASM and S files.
1. Remove ASM from all modules.
2. Remove S files from the drivers only.
3. https://bugzilla.tianocore.org/show_bug.cgi?id=881
After NASM is updated, S files can be removed from Library.

When compiling with any ARM toolchain and Os, registers can get
trashed when returning for the second time from SetJump because GCC
only handles this correctly when using standard names like 'setjmp' or
'getcontext'. When different names are used you have to use the
attribute 'returns_twice' to tell gcc to be extra careful.
example:
extern int FN_NAME(void*);
void jmp_buf_set(void *jmpb, void (*f)(void))
{
if (!FN_NAME(jmpb))
f();
}
this code produces this wrong code with Os:
00000000 <jmp_buf_set>:
0: e92d4010 push {r4, lr}
4: e1a04001 mov r4, r1
8: ebfffffe bl 0 <nonstandard_setjmp>
c: e3500000 cmp r0, #0
10: 01a03004 moveq r3, r4
14: 08bd4010 popeq {r4, lr}
18: 012fff13 bxeq r3
1c: e8bd4010 pop {r4, lr}
20: e12fff1e bx lr
The generated code pushes backups of r4 and lr to the stack and then
saves all registers using nonstandard_setjmp.
Then it pops the stack and jumps to the function in r3 which is the
main problem because now the function can overwrite our register
backups on the stack.
When we return a second time from the call to nonstandard_setjmp, the
stack pointer has it's original(pushed) position and when the code
pops r4 and lr from the stack the values are not guaranteed to be the
same.
When using a standard name like setjmp or getcontext or adding
'__attribute__((returns_twice))' to nonstandard_setjmp's declaration
the code looks different:
00000000 <jmp_buf_set>:
0: e92d4007 push {r0, r1, r2, lr}
4: e58d1004 str r1, [sp, #4]
8: ebfffffe bl 0 <setjmp>
c: e3500000 cmp r0, #0
10: 059d3004 ldreq r3, [sp, #4]
14: 01a0e00f moveq lr, pc
18: 012fff13 bxeq r3
1c: e28dd00c add sp, sp, #12
20: e49de004 pop {lr} ; (ldr lr, [sp], #4)
24: e12fff1e bx lr
Here the problem is being solved by restoring r3 from the stack
without popping it.

The new definitions include two structures
IA32_TASK_STATE_SEGMENT
IA32_TSS_DESCRIPTOR
two macros
IA32_GDT_TYPE_TSS
IA32_GDT_ALIGNMENT
and one API
VOID
EFIAPI
AsmWriteTr (
IN UINT16 Selector
);
They're needed to setup task gate and interrupt stack table for stack switch.

The leading underscore (i.e. '_') before the names of some BaseLib library
API in ASM/NASM files is unnecessary. It will cause link error with GCC
tool chains.
