The fix for golang/go#11541 made the assertion that getting an invalid
Numeric_constant after evaluating an invalid constant must result in
an error in a binary expression. However, a Numeric_constant can be
invalid if it is unset, which occurs when either operand cannot be
converted to the right type. These errors are issued after the
Numeric_constant is lowered.

This patch removes the gas configure option:

to enable compressed debug sections for gas, gold or ld by default. At
the moment, this configure option is ignored by gold and ld. For x86

-miamcu specifies how parameters are passed to functions and how value
is returned from a function. Inside function, we can use instructions
supported by -march=XXX. -miamcu -march=haswell can generate x87, SSE
and AVX instructions as long as the IA MCU psABI is followed. But since
Lakemont processor doesn't support x87 instructions, we shouldn't
generate x87 instructions with -march=lakemont. This patch separates
code generation from -miamcu and makes -march=lakemont not to generate
x87 instructions.
