The definition and most uses of MAKECONTEXT_STACK_TOP were removed in
https://golang.org/cl/88660043, which removed support for Solaris 8/9.
One use of MAKECONTEXT_STACK_TOP was accidentally left in the source
code. Remove it now.

Some systems, such as ia64 and PPC, require that a ucontext_t pointer
passed to getcontext and friends be aligned to a 16-byte boundary.
Currently the ucontext_t fields in the g structure are defined in Go,
and Go has no way to ensure a 16-byte alignment for a struct field.
The fields are currently represented by an array of unsafe.Pointer.
Enforce the alignment by making the array larger, and picking an offset
into the array that is 16-byte aligned.

libgcc complex multiply is meant to eliminate excess
precision from certain internal values by forcing them to memory in
exactly those cases where the type has excess precision. But in
https://gcc.gnu.org/ml/gcc-patches/2014-09/msg01894.html I
accidentally inverted the logic so that values get forced to memory in
exactly the cases where it's not needed. (This is a pessimization in
the no-excess-precision case, in principle could lead to bad results
depending on code generation in the excess-precision case. Note: I do
not have a test demonstrating bad results.)
Bootstrapped with no regressions on x86_64-pc-linux-gnu. Code size

Improve aarch64_legitimize_address - avoid splitting the offset if it is
supported. When we do split, take the mode size into account. BLKmode
falls into the unaligned case but should be treated like LDP/STP.
This improves codesize slightly due to fewer base address calculations:
int f(int *p) { return p[5000] + p[7000]; }
Now generates:
f:
add x0, x0, 16384
ldr w1, [x0, 3616]
ldr w0, [x0, 11616]
add w0, w1, w0
ret
instead of:
f:
add x1, x0, 16384
add x0, x0, 24576
ldr w1, [x1, 3616]
ldr w0, [x0, 3424]
add w0, w1, w0
