Subject: Remove uses and caches of the target machine and subtarget from
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=72a5b2a14e2e1b2bda5205e7634c070e221ec7f7;p=platform%2Fupstream%2Fllvm.git

Remove uses and caches of the target machine and subtarget from
both MSP430InstrInfo and MSP430RegisterInfo. Remove unused member
variable StackAlign from MSP430RegisterInfo. Update constructors
accordingly.
