Mark the exception handlers with "dotraplinkage" to hide the
calling convention differences between i386 and x86_64.

Split out math_error from do_coprocessor_error and simd_math_error
from do_simd_coprocessor_error, like on i386. While at it, add the
"error_code" parameter to do_coprocessor_error, do_simd_coprocessor_error
and do_spurious_interrupt_bug.
This does not change the generated code, but brings the declarations in
line with all the other trap handlers.

Currently a SIGTRAP can denote any one of below reasons.
- Breakpoint hit
- H/W debug register hit
- Single step
- Signal sent through kill() or rasie()
Architectures like powerpc/parisc provides infrastructure to demultiplex
SIGTRAP signal by passing down the information for receiving SIGTRAP through
si_code of siginfot_t structure. Here is an attempt is generalise this
infrastructure by extending it to x86 and x86_64 archs.

declared do_page_fault() in asm-x86/trap.h for both X86_32 and X86_64
removed do_invalid_op declaration from mm/fault.c as it is already declared in asm-x86/trap.h

This patch is the result of an automatic script that consolidates the
format of all the headers in include/asm-x86/.
The format:
1. No leading underscore. Names with leading underscores are reserved.
2. Pathname components are separated by two underscores. So we can
distinguish between mm_types.h and mm/types.h.
3. Everything except letters and numbers are turned into single
underscores.

Declaring x86 traps under one hood.
Declaring x86 do_traps before defining them.
