Fix PR16193 - gdbserver aborts.
The MPX patch has broken the I386_XSTATE_SIZE macro. For AVX machines,
it ends up returning I386_XSTATE_SSE_SIZE. Where it first reads
I386_XSTATE_AVX_SIZE, it should have read I386_XSTATE_AVX:
#define I386_XSTATE_SIZE(XCR0) \
(((XCR0) & I386_XSTATE_BNDCFG) != 0 ? I386_XSTATE_BNDCFG_SIZE \
: (((XCR0) & I386_XSTATE_BNDREGS) != 0 ? I386_XSTATE_BNDCFG_SIZE \
- : (((XCR0) & I386_XSTATE_AVX_SIZE) != 0 ? I386_XSTATE_AVX_SIZE \
+ : (((XCR0) & I386_XSTATE_AVX) != 0 ? I386_XSTATE_AVX_SIZE \
: I386_XSTATE_SSE_SIZE)))
The patch goes a step further and improves readability of the macro,
by adding a couple other auxiliary macros.
