[Patch] Add mips*-linux* catch syscall support.

[Patch] Add mips*-linux* catch syscall support.

[David Daney]

This patch adds catch syscall support for all three MIPS Linux ABIs 
(o32, n32 and n64).

For the most part this works as expected, except for one small detail. 
The MIPS Linux syscall ABI passes the syscall number in register v0 when 
making a syscall, but it also uses the same register to return 
information back from the syscall.  This clobbering of the syscall 
number is currently not well handled by GDB.  We PASS all the tests for 
'(call to syscall ???)', but FAIL those for (returned from syscall ???), 
because GDB expects to be able to obtain the syscall number on syscall 
exit.  For MIPS Linux it will never be available.

I think the real fix for this is to improve the core 'catch syscall' 
support so that it can either remember the syscall number, or not try to 
print out bogus information, but that would be something for a different 
patch.

Tested on mips-linux, and mips64-linux.

OK to commit?

Why not just use alloca or XALLOCAVEC here?

Because I copied the code from PPC, and that is what was done there.

Since we know that the maximum size is 8 bytes, I could just allocate a 
fixed size array on the stack.  That would simplify things quite a bit.

I will test that and generate a revised patch.

That's typically what I do for code that supports both 32-bit and
64-bit registers in the GDB targets I (sort of) maintain (i386/amd64,
sparc/sparc64).
